Product Description
Zircon mulite firebrick is made of high quality mullite sand and zircon powder as the main material, zircon mulite refractory brick is produced by the production process of molding by high temperature and sintered by high temperature. zirconia mulite firebrick has the characteristics of high bulk density, high strength, good thermal shock resistance, high temperature erosion resistance and good slag resistance. zirconia mulite fire brick is mainly applied to the bottom of the glass kiln pool, paving brick and kiln superstructure.
Properties of Zircon Mullite Brick
- High strength,
- Good slag resistance,
- High bulk density,
- Good thermal shock resistance,
- High temperature erosion resistance.
- anufacturing Process of Zircon Mullite Brick
Zirconium mulite fire brick selectes high quality mullite sand and zircon powder as its main raw material. Molded by high pressure and sintered by high temperature, the zirconium mulite firebrick has such advantages as high bulk density, high strength, good thermal shock resistance, high temperature erosion resistance and good slag resistance. zircon mulite blocks is mainly used in long-life orifice rings, tank bottom, tank superstructure, perfume bottle feeder, covers for working tanks and soda lime glass.
Classification of Zircon Mullite Brick
1.Zirconium fire mullite made of industrial alumina and zircon
2.Zirconium fire mullite made of high alumina bauxite and zircon
3.Fused granules combined with zirconium mullite firebricks
