■ Introduction:
Zirconium mullite high tempreture shaped brick is a high-performance refractory material that is made by sintering zirconia and mullite raw materials at high temperatures. The Zirconium sintered mullite shaped brick has excellent thermal shock resistance, high mechanical strength, and good chemical stability.
The Zirconium fused mullite shaped brick is widely used in high-temperature kilns and furnaces, such as the petrochemical industry, metallurgical industry, and ceramics industry. It is used as linings for gasifiers, reactors, and incinerators, as well as for high-temperature processing of non-ferrous metals and glass.
The advantages of Zirconium mullite high tempreture shaped brick include its high refractoriness, low thermal conductivity, and low thermal expansion. Zirconium sintered mullite shaped brick can withstand temperatures up to 1800°C, making it suitable for use in extreme high-temperature environments. Its high strength and resistance to thermal shock make it ideal for use in areas where sudden changes in temperature occur.
Zirconium fused mullite shaped brick is a high-quality refractory material that can withstand high temperatures and thermal shock. It is widely used in high-temperature kilns and furnaces in various industries due to its excellent properties.
