AL-SI Carbide Carbon Brick, also known as ASC Brick, is a high-performance refractory product made from premium raw materials such as fused or sintered corundum, high-grade bauxite clinker, graphite, and high-purity silicon carbide (SiC). These materials are bonded with resin and shaped using high-pressure forming technology, followed by low-temperature curing at 210°C to ensure optimal integrity and performance.

Production Details
Silicon Nitride Bonded Silicon Carbide Bricks are manufactured through a high-temperature sintering process. High-purity silicon carbide (SiC) is used as the main raw material, combined with silicon nitride (Si₃N₄) as the bonding phase. The mixture is shaped under high pressure and sintered at elevated temperatures to ensure optimal bonding and mechanical integrity.
