Refractory Kiln Shelf High Temperature Resistance Mullite Cordierite Ceramic Heating Disc

Product Description

Cordierite-Mullite Disc is composed of cordierite, mullite and glass phase. Due to the high temperature resistance of mullite and the low expansion of cordierite, Cordierite-Mullite slab has excellent thermal shock resistance, good strength .

It is widely used in porcelain, glass panel industry.

Cordierite Ceramic main raw material include the talc, clay, alumina, feldspar general manufacturing ceramic technology. Its sintering range is narrower, it is difficult to obtain a dense body. It often used chlorite, magnesium carbonate, barium carbonate, zirconium silicate, zirconium dioxide, boron oxide, spodumene as the additives capable because of lowering the sintering temperature, sintering temperature range to expand and improving its dielectric properties. Burner may be used as coil bobbin, arc-resistant electrically insulating material effects,base material of the composite , electric apparatus insulating nozzle ect.

2. Features of cordierite ceramic disc: Ceramic disc that hold the heating elements. In combination with the radiant tubes which delivers high power, avoid refractory corrosion and avoid the gas impurity in process materials. These design for long life and maintenance free operation. The element can be provided in ferritic alloys up to 1250° C and NiCr alloy up to 1100°C materials.

3. Applications of mullite disc:    
1). Ceramic shaft for aquarium equipment filter pump.
2). Ceramic plunger for high pressure cleaner.
3). Wearlessness,resistant acid-base and high intensity ceramic  assembly apply to petroleum ,chemical and chemical industry.
4). Wearlesness, corrosion resistance parts apply to precision machine.
5). They are also widely used in all kinds of ovens.
