Product Description

Casting Zirconium Mullite Brick Refractory Product for Petrochemical Industry
The description:

Zirconium mullite brick is a fused cast refractory product with mullite and zirconia as raw materials. Zirconium mullite cast brick has dense crystal structure, high softening temperature under load, good thermal stability, high mechanical strength at room temperature and high temperature, good wear resistance, good thermal conductivity, and excellent resistance to erosion.

 

Sintered zirconium mullite brick is a high-grade refractory brick made of industrial alumina and zirconite concentrate as raw materials, and ZrO2 is introduced into the mullite matrix through the reaction sintering process. The reaction equation is as follows: 3A12O3 ten 2ZrSiO4→3 A12O3·2SiO2+2ZrO2 Mullite ceramics have many excellent characteristics, such as high temperature resistance, thermal shock resistance, high temperature creep resistance and good chemical stability.

When ZrO2 is introduced into mullite ceramics, the high temperature mechanical properties of mullite materials can be greatly improved by the phase transition toughening of ZrO2. ZrO2 can promote the sintering of mullite materials. The addition of ZrO2 can accelerate the densification and sintering process of ZrO2 materials due to the generation of low melts or the formation of vacancy. When the molar fraction of ZrO2 is 30%, the relative bulk density of the billet sintered at 1530ºC can reach 98%. The strength reaches 378MPa and the toughness reaches 4.3MPa·m1/2. The strengthening and toughening mechanisms of ZrO2 materials with different compositions are different.
