Product Description

　　This product series is manufactured using high-grade, high-alumina as the primary raw material, combined with carefully selected additives and produced via the polyhydrogen burnout method. The resulting products boast exceptional strength, excellent thermal shock resistance, minimal post-firing dimensional change, and low thermal conductivity—making them ideal for use as linings or insulation layers in a wide range of industrial kilns across industries such as metallurgy, machinery, ceramics, and chemical processing. They are particularly well-suited for applications where resistance to slow corrosion by molten solutions is required. The recommended operating temperature ranges below 1400°C.
