Alumina Tiles For Industrial Applications

Alumina tiles protect equipment surfaces from wear-causing interactions between shear and sliding abrasives and equipment surfaces, prolonging operational lifespans while decreasing downtime costs. They also resist corrosion and can be sanitised to rid of harmful bacteria or microorganisms that might compromise them.

Utilising a LECO moisture analyzer enables you to accurately gauge the moisture content in alumina tiles, and ensure they are ready for use. Excess moisture can negatively impact their performance.

Abrasive Resistance

Alumina tile is the go-to ceramic material for industrial lining applications due to its impressive resistance to erosion and corrosion owing to its diamond hardness and mechanical strength. Alumina tiles come in various sizes, shapes, thicknesses and materials to meet each application’s specific requirements and are highly sanitizable allowing it to line equipment that may come into contact with food or potentially harmful microorganisms without risk.

Abrasion and wear are both leading causes of equipment deterioration and costly downtime, as well as detrimental to its lifespan. To help prolong its longevity, CRGI’s Enlast alumina ceramic liners have been specifically developed to prevent destructive interactions between abrasive materials and equipment surfaces, significantly increasing its lifespan.

These durable ceramic liners can easily be cut to suit your equipment. Plus, they can be welded or bolted in place for quick installation and don’t filter into products or contaminate them with harmful particles! Plus they’re nonporous – great news if your products require filtering!

Thus, they provide an ideal solution to corrosion, erosion, sliding or impact abrasion issues in different industries, including power generation, metallurgy, coal mines and pulp and paper production.

Alumina ceramics are among the hardest, toughest and abrasion resistant materials on Earth – only rivaled by silicon carbide, boron carbide, and diamond. Furthermore, they’re highly refractory and extremely long-wearing; making them perfect for high wear applications.

Alumina is highly resistant to acid attack from both sulfuric and hydrochloric acids and temperatures up to 1000 degrees Celsius, making it the ideal material for use as furnace and kiln linings at high temperatures.

Corrosion Resistance

Alumina ceramic tiles boast high resistance to corrosion, meaning that they are capable of withstanding harsh minerals and chemicals without becoming damaged over time. This makes them the ideal material to use in bulk materials handling equipment used for mining and coal processing, steel production and many other industrial applications. Corrosion damage can cause equipment failure which leads to costly lost productivity; ceramic tile linings protect steel pipes against wear-and-tear, thus prolonging their lives by protecting from wear-and-tear and prolonging corrosion damage.

Alumina’s inertness makes it an excellent refractory material, as its hard surface doesn’t react with liquid metals and doesn’t etch or degrade in most acids such as sulfuric, hydrochloric and nitric acids.

Alumina boasts excellent thermal stability and low coefficient of expansion, making it ideal for use in high-temperature environments such as furnaces and kilns as well as glass drawing crucibles. Furthermore, alumina doesn’t react with liquid silica and has excellent thermal insulation properties.

Graphene boasts outstanding electrical properties and is an excellent dielectric for high-frequency applications up to 1 GHz, featuring low loss factor and stiffer structure than glass, making it suitable for pressure sensor insulators, semiconductor feedthroughs, X-ray component feedthroughs as well as high voltage bushings and implantable medical device products.

ISO Pressed Alumina Tiles are an ideal choice for applications where impact and sliding abrasion pose major concerns. Constructed of high-purity alumina crystals bonded together with crystalline alumina silicate, these dense ceramic liners offer exceptional resistance against impact and sliding abrasion and come in various thicknesses to suit various industrial needs.

High Temperature Resistance

Alumina is an extremely hard ceramic that resists corrosion, abrasion, impact and extreme temperatures. This property makes it suitable for protecting equipment against erosion and abrasion in mining operations, general industrial settings or food processing environments as well as being utilized as an effective lining material in coal, steel or pulp and paper production plants.

Alumina’s unique atomic structure prevents it from warping or expanding under extreme heat, providing it with a distinct advantage over many materials, particularly metals, which tend to expand rapidly under such temperatures. Furthermore, alumina bonds are stronger than those in other materials so can withstand higher temperatures without damage being done to them.

Pressed alumina ceramics are an increasingly popular choice in industrial applications, offering excellent abrasion-resistance and hermeticity properties. As such, they make ideal lining material for wear nozzles, blood valves, electrical components, insulators, weldable systems with high impact or thermal stress requirements and brazing assemblies as well as serving as an effective insulator in microwave windows, laser equipment, X-ray tubes.

Impact Resistance

Alumina ceramic tiles have the strength to withstand large impacts without shattering, making them ideal for use as wear resistant linings in equipment used for transport, processing or storing materials. By protecting equipment surfaces against friction between abrasive material and components of equipment components, alumina ceramic tiles extend machine lifespan while decreasing downtime costs significantly.

Alumina boasts a high melting point, strong mechanical strength and low thermal expansion coefficient. Chemically stable and resistant to most acids and alkalis; with the exception of certain hydrofluoric acid solutions.

These properties make polyimide an excellent material choice for applications requiring abrasion-resistance such as nozzles, blood valves and electrical insulation applications. Furthermore, it can be manufactured into precise machined parts with high hermeticity requirements such as pressure sensors, vacuum pumps and electron tube and laser component feedthroughs.

Alumina ceramic has exceptional impact resistance due to the strength and density of its grain structure and matrix material. A high elastic modulus makes alumina ceramic an effective material that dissipates stress energy generated by impacts into manageable increments, thus mitigating any damage induced by them.

Circular laser cutting on alumina produces results where the temperature decays more rapidly around the hole circumference than elsewhere, which reflects how energy absorbed at impact sites by alumina converts to internal stresses that contribute to the formation of striations at its edges. However, this effect can be reduced significantly when supported by aluminium or plastic reinforced fibre composites.

Chemical Resistance

Alumina tiles are highly resistant to chemicals and minerals that cause corrosion, as well as high temperatures, making it suitable for industrial equipment like chutes and hoppers subject to heavy wear and tear. Due to its resistance against corrosion, Alumina is also often chosen as the liner in furnaces or kilns.

Corrosion resistance is of primary concern for materials used in mining industry applications, including alumina ceramic liners. They must withstand harsh chemical environments that include coal processing plants to protect equipment against wear-and-corrosion damage; or steel production facilities where metal contaminants pose threats.

Alumina ceramics’ resistance to corrosion depends largely on their chemical makeup; silicate or non-oxide ceramics tend to exhibit lower corrosion rates than their oxide counterparts. Aside from its composition, other factors, including concentration of acidic/alkaline solutions, and exposure temperature also impact its corrosion rate.

Studies on the effects of laser straight cutting of alumina are being undertaken using XRD and scanning electron microscopy (SEM), with specific attention paid to its microstructure. SEM images of cut sections reveal no large defect sides compared to metals; however, SEM micrographs of laser-cut surfaces show instabilities associated with melt flow at the kerf surface during cutting that causes striations at low depth levels with well-ordered and closely spaced striations patterns that do not result in localized thermal erosion. This is quite different from metal micrographs which often show deep-seated striations which causes localized thermal erosion.
