Alumina is used across industrial applications where heat resistance, hardness, wear performance, purity and material consistency are important. The Alumina Company serves refractory, abrasive and technical ceramic markets with a portfolio of alumina-based products selected according to application and processing requirements.
Refractory systems operate under demanding thermal conditions. Alumina-based raw materials can be used in bricks, castables and other refractory formulations where high-temperature stability and controlled material properties are required. Depending on the formulation, relevant TAC materials can include specialty calcined alumina, tabular alumina, alumina-magnesia spinel and calcium aluminate cement. See the refractories market page for more detail.
Hard fused alumina materials such as white fused alumina and planned brown fused alumina are associated with bonded and coated abrasives, grinding, surface preparation, blasting, polishing and lapping applications. Grade selection depends on the abrasive process, desired cutting behavior, contamination limits and particle-size requirements. See the abrasives market page.
Technical ceramic applications can require high-purity alumina and carefully controlled material characteristics. The right grade depends on powder processing, forming route, firing conditions and the intended performance of the finished ceramic component. TAC’s specialty calcined alumina portfolio is relevant to these discussions. See the technical ceramics market page.
Refractory formulations can use calcined alumina, tabular alumina, fused alumina, alumina-magnesia spinel and calcium aluminate cement depending on the design and service conditions.
White fused alumina and brown fused alumina are common fused-alumina families for abrasive applications. The appropriate grade depends on the abrasive process, desired toughness, purity and grain size.
Technical ceramics often use high-purity alumina powders with tightly controlled particle characteristics. The required material depends on forming, firing and finished-component performance requirements.
Start with the application, operating conditions, required chemistry or purity, particle-size requirements, processing route, expected volume and quality documentation needs. TAC can then discuss relevant product categories and supply requirements.
