1,Main performance parameters of High Purity Fused Mullite
2,Product description
High purity fused mullite is a high-grade refractory raw material synthesized by high-purity raw materials at high temperature in the electric arc furnace. The product after electrofusion is white gray and massive. After high-temperature sintering, the product is white, and the physical and chemical indexes of the product remain unchanged
High purity, low Fe2O3 and other impurities, low apparent porosity and high density. It has high creep resistance and thermal shock resistance. It is an ideal raw material for manufacturing low Japanese refractory bricks, torpedo lining bricks and high-temperature kiln refractory bricks. It is also a high-grade refractory raw material for producing toughened mullite ceramic products and unshaped refractory products
The high-purity fused mullite is light gray, which is due to the presence of metallic silicon and a small amount of iron in the frit, and a small amount of SiO2 is enclosed in the frit due to rapid cooling and rapid surface solidification, making the mullite frit colored. Then it is fired above 1480 ℃, and the high-purity fused mullite becomes white
Compared with sintered mullite, high-purity fused mullite has better high-temperature mechanical properties and corrosion resistance
3,Main characteristics of High Purity Fused Mullite
Compared with sintered mullite, fused mullite has the following main characteristics
1) The product has high purity and low Fe2O3 and other impurities
2) Good compactness, high density and low porosity
3) Good creep resistance and thermal shock resistance
4) High temperature bending strength, high compressive strength
5) Good corrosion resistance
4,Main purpose
It can be used as an ideal raw material for producing low creep refractory bricks, high-grade kiln furniture bricks and high-grade unshaped refractory products
