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.
