Product 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 ºC. The starting temperature of load softening is 1600 ~ 1700 ºC. Good thermal shock resistance. There are two kinds of sintered mullite bricks and fused mullite bricks.Our mullite brick series is industry-leading in applications such as petrochemicals, metals, ceramics, and glass, saving a lot of energy for many markets.

Mullite Insulation Brick Features

Mullite bricks has the advantages of high porosity, small bulk density, good insulation effect, and long service life. With high refractoriness, mullite insulation bricks can be directly exposed to flames. They have the characteristics of light weight, high strength, low thermal conductivity, good thermal shock resistance.For various industrial kilns, it is an important energy-saving, insulation, and refractory material.

1. Good integrity with furnace lining, long service life, easy operation, could be shaped freely
2. Product specification: standard form, normal standard, shaped and special shaped bricks.
3.Large bricks or slabs and special shapes available
4. Can be used in various kilns because of its cheapness. Among all of the refractory materials, it is the most widely used.

Product Application

Mullite Insulation Brick Applications

Mullite insulation bricks refractory material can be used in linings or heat-insulating materials of the industries, such as, ethylene pyrolysis furnaces, tubular furnaces,reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc.

• Aluminium anode bake furnaces, primary electrolytic cells, holding and melting furnaces and secondary remelt furnaces
