Fused cast alumina bricks are categorized into three types based on the differing proportions of alpha-phase (α) and beta-phase (β) corundum: fused cast α-β alumina block, fused cast β alumina block, and fused cast α alumina block.

Their interlocking crystalline structure, formed by intertwined crystallization, creates an extremely dense matrix. This structure delivers outstanding resistance to strong alkalis.

These bricks are ideally suited for high-grade glass furnaces, particularly in areas such as:

l Working end walls

l Cover blocks

l Gating systems

l Channels

They deliver excellent performance and offer good cost-effectiveness.
