The main properties of alumina ceramics are low electric conductivity, high strength and chemical resistance. In addition, their melting point is very high and they exhibit extreme hardness (rated at 9 Mohs). These qualities make alumina an excellent choice for various engineering applications.

Transparent alumina ceramics

Transparent alumina ceramics are a class of glassy and crystalline ceramic materials that can be used for optical applications. This type of material has high surface area and can be used in bulk solid-state components.

Calcined alumina

Calcined alumina ceramics are products of the calcination of aluminium hydroxide to produce aluminium oxide. These materials are used in various ceramic applications due to their unique properties. These include high strength and compression strength, good thermal conductivity and dielectric strength, resistance to thermal shock, and low cost. These products are commonly used in the ceramic, glass, and refractory industries. They are also used in the chemical, paint, and rubber industries, and in synthetic zeolite production.

Tabular alumina ceramics

The global tabular alumina market is consolidated and dominated by a handful of leading vendors. These vendors are renowned for their expertise in their product categories. These suppliers produce tabular alumina in specialized units. The manufacturing facilities vary depending on the latest technology, availability of raw materials, and demand for finished products. Manufacturers are also increasingly focusing on customized products and partnerships with end users.

Activated alumina

Activated alumina is a highly porous material, which bonds to liquids and gases in a wide variety of applications. It is also nontoxic and odorless. It can sustain high temperatures and acidic environments. Moreover, it exhibits high mechanical strength and low wear.

Calcined alumina powder

Calcined alumina powder is a white powder that has good flow-ability and performance stability. It is used in a variety of applications including aluminous refractory and ceramics. This alumina is available in bonded, coated, and free-grinding grades. Its abrasive properties make it suitable for grinding ceramics.

Activated alumina catalysts

Activated alumina catalysts are used for various industrial processes. They can enhance the mechanical properties of ceramics and provide a wide range of applications. The active ingredient is a white spherical powder that is insoluble in water, organic solvents, or acids. It can also withstand sulfate poisoning and exhibits high strength.

Activated alumina substrates

Activated alumina is an excellent adsorbent, with excellent mechanical, thermal, electrical and thermal-electrical properties. It is non-toxic, tasteless, non-corrosive, non-flammable and has a high ion exchange capacity. It is also very hard and strong, with a low coefficient of friction. It also exhibits excellent wear and corrosion resistance, and does not cause softening, swelling, powdering or cracking.
