Cordierite-Mullite Crucible for Ceramic Sintering and Material Processing
PRODUCT PARAMETERS
Description
Cordierite-Mullite Crucible
Cordierite-Mullite crucibles are manufactured using high-quality industrial cordierite and mullite powders through a scientific formulation, high-pressure molding, and high-temperature sintering process. They combine the excellent thermal shock resistance of cordierite with the good high-temperature resistance and mechanical strength of mullite. The product’s bulk density is generally ≥2.0 g/cm³, and the maximum service temperature can reach 1400℃.
With its low coefficient of thermal expansion, excellent thermal stability, and good chemical corrosion resistance, it is an ideal refractory vessel for medium- and high-temperature sintering processes.
Product Features
- Composite Material, Synergistic Performance Optimization
Made using industrial cordierite powder and mullite powder through a rigorous compounding process, then calcined at high temperature. It combines the excellent thermal shock resistance of cordierite with the high-temperature strength and mechanical properties of mullite, the complementary advantages of the two materials forming an ideal composite refractory material.
- Excellent Thermal Shock Resistance
The cordierite component imparts a low coefficient of thermal expansion to the crucible, preventing cracking and peeling under frequent temperature fluctuations. This is particularly suitable for batch production processes requiring repeated rapid heating and cooling, significantly extending the crucible’s service life.
- Good High-Temperature Resistance and Mechanical Strength
The mullite component provides excellent high-temperature structural stability and mechanical strength. With a maximum operating temperature of 1400℃ and a bulk density exceeding 2.0 g/cm³, it does not deform or collapse at high temperatures, meeting the requirements for long-term high-temperature use.
- Resistance to Alkaline Corrosion
It exhibits excellent corrosion resistance in alkaline environments, making it suitable for handling alkaline fluxes and materials. It performs exceptionally well in processes such as lithium-ion battery cathode material precursor processing and alkaline glaze melting.
