European Producers of Specialty Aluminas (EPSA)

Specialty Aluminas are synthetic products that have a variety of forms and an even wider range of uses. These are often identified as non-metallurgical aluminas to distinguish from smelter grade alumina, the principal feedstock for Aluminium metal production. Usually deriving from bauxite ore, subsequent process stages can produce Aluminium trihydroxide (ATH), activated aluminas, boehmite, calcined alumina, tabular alumina and fused alumina products. Careful process control also produces a further wide variety of forms and grades within each of these categories.

Particular to each of these products are critical properties that make these key components in a broad range of applications. From the flame retardancy of ATH as a filler in plastic and rubber to calcined alumina in ceramic and refractory materials due to its mechanical strength, wear resistance, thermal, electrical and chemical properties in the finished components. Further sintering of alumina creates Tabular alumina, a key material for refractory products where high temperature strength and corrosion resistance are essential. Fused alumina exhibits superior hardness in addition and is an ideal material for bonded and coated abrasives, pressure blasting as well as refractories and ceramics. It is also used in wear resistance floorings and tiles.
