"High-alumina" refers to its chemical composition containing a high Al₂O₃ (alumina) content, typically exceeding 65% and reaching up to 75% in premium grades. This alumina concentration is the decisive factor for its structural strength.

"Mullite" denotes its primary crystalline phase—a needle-like or columnar crystal structure that remains exceptionally stable at elevated temperatures. This morphology forms a robust network skeleton, endowing the brick with superior thermal shock resistance and corrosion resistance.

Performance & Advantages: 

• High refractoriness;

• High refractoriness under load;

• Superior thermal shock resistance;

• Chemical corrosion resistance.

1. • Applications：

Primarily applied in the iron & steel industry, building materials sector, ceramics manufacturing, non-ferrous metal smelting, and petrochemical industry.
