Description
Fused and re-sintered mullite bricks are manufactured using high-purity fused raw materials, ultrafine powder, and composite additives. These components undergo high-pressure forming and high-temperature sintering processes to create bricks with exceptional properties. The mullite bricks possess high strength, elevated refractoriness under load, remarkable thermal stability, and other excellent features.
