Reactive Alumina
Common in refractory castables (LCC/ULCC), technical ceramics, and refractory coatings where high reactivity is essential. Improves bonding, densification, and enables lower sintering temperatures. High surface area and ultra-fine particle size enhance reactivity during sintering.
Soft Calcined Alumina
Widely used in refractory castables, ceramic bodies, and polishing applications. Delivers balanced packing, strength, and stable performance with controlled reactivity. Medium particle size supports good packing behavior and consistent processing.
Hard Calcined Alumina
Primarily used in abrasives, refractory aggregates, and ceramic fillers. Provides high hardness, wear resistance, and stability with low reactivity. Coarse, stable alpha phase (α-Al₂O₃) ensures durability under high-temperature conditions.
Alumina Ball
Used in grinding, milling, and high-temperature environments such as kilns and reactors. Offers high hardness, excellent wear resistance, and chemical stability. Functions as grinding or support media, ensuring consistent performance and long service life under harsh conditions.
