Product Description
Overview
 
Products Description
Mullite Insulating Brick Description : Mullite bricks are high alumina refractories with mullite as the main crystal phase. Generally, the alumina content is between 65% and 75%, and the refractory of mullite brick is relatively high, reaching above 1790 ℃. The starting temperature of load softening is 1600 ~ 1700 ℃. Good thermal shock resistance. There are two kinds of sintered mullite bricks and fused mullite bricks.Standard size 230 x 114 x 65 mm or according to customer requirements.
 
Characteristics of Mullite Insulation Bricks
1. Mullite insulation bricks have high fire resistance and can be directly exposed to flames.
2. Mullite fire bricks have the characteristics of light weight, high strength, low thermal conductivity and good thermal shock resistance.
3. Mullite bricks have the advantages of high porosity, small bulk density, good thermal insulation effect, and long service life.
4. Mullite refractory bricks are important energy-saving, thermal insulation and refractory materials for various industrial kilns.
