Product Description

Description of Zirconia mullite refractory brick
Sintered zirconium mullite brick is a special refractory material made by using industrial alumina and zircon concentrate as raw materials and introducing zirconium oxide into the mullite matrix through a reactive sintering process. Introducing zirconia into mullite bricks, and using the phase change toughening of zirconia can greatly improve the high-temperature mechanical properties of mullite materials. Zirconia can promote the sintering of mullite materials. The addition of ZrO2 can accelerate the densification and sintering process of ZTM materials due to the generation of low melting point substances and the formation of vacancies.
