Mullite Ceramic Plate
Cordierite Mullite Plate / Slab / Sheet / Shelf / Saggar / Crucible
Product Description:
Cordierite mullite is a composite material composed of cordierite phase, mullite phase, and glass phase, which has excellent thermal shock stability and strong high-temperature flexural strength. Cordierite mullite kiln furniture is the most ideal refractory material under medium temperature conditions, widely used in daily ceramics, sanitary ware, building ceramics, high-voltage electric ceramics, magnetic materials, powder metallurgy, powder calcination, technical ceramics and other industries.
Cordierite mullite conventional kiln furniture is also called as primary kiln furniture, is mainly used for the construction of kiln car construction, including solid plate, porous plate, grooved plate, hollow slab, pillars, pillar caps, connectors, etc. The products are used in different industries and have strong universality.
Advantages：
1. It has excellent antioxidant properties and can be used under the oxidation and reduction atmospheres of firing ceramic
2. High temperature compressive and flexural strength, the plate can be used on one side for a long time without flipping over and deformation.
3. It has good resistance to shock cold and heat, and is not easy to crack during use.
4. High density, a smooth surface, and does not form slag during use.
5. The temperature range for firing can be used within 1300 ° C.
6. Extremely high thermal conductivity, excellent high-temperature corrosion resistance, and excellent wear resistance.
7. High strength, based on the same specifications and the premise of ensuring long-term use without deformation, the thickness of plate is thin, which can maximize the utilization efficiency of the kiln and save energy.
Application：
The cordierite mullite products has cordierite mullite plate, cordierite saggars,cordierite mullite fish shaped plate, cordierite mullite slab, etc. The cordierite mullite kiln furniture is used in combination with reaction sintered silicon carbide square beam. The products are widely used in various daily ceramics, sanitary ceramics, sanitary ware, building ceramics, high-voltage electric porcelain, electronic ceramics, grinding wheels, magnetic materials, powder metallurgy, powder calcination and other industries etc.The kilns are suitable for tunnel kilns, shuttle kilns, roller kilns, pusher kilns, etc.
