Choose the solution that fits your production scenario
Crucible匣钵
Refractory base material for high-temperature load-bearing components
Crucibles and saggers operate under prolonged high-temperature load conditions. The purity and particle size distribution of aggregates and fine powders in the formulation directly impact the product's thermal stability. Using mullite sand powder as the base material helps control volume changes and maintain structural integrity.
- Low Fe₂O₃ content minimizes high-temperature impurity effects.
- Aggregates and fines available as a complete set
- Supports gradation adjustment based on product manufacturing processes
Stainless Steel Valves for Investment Casting
Refractory materials for shell face and back layers
In investment casting, the shell face coat material significantly affects surface roughness and dimensional accuracy of castings. Mullite powder is suitable for face coat slurries and stucco applications, while sand materials are used in backup layers to enhance high-temperature shell strength.
- The top layer uses fine powder with a concentrated particle size distribution.
- Full-specification supply of sandblasting and backing sand materials
- Available in customer-specific formulation ratios
Automotive engine block
Casting Molding Materials & Accessories
Engine block castings require consistent dimensional accuracy and surface quality. Stable high-temperature performance and batch-to-batch consistency of molding materials are prerequisites for mass production stability. Mullite sand serves as a refractory component in both molding and core-making materials.
- Low batch-to-batch variability ensures stable mass production.
- Complete range of particle sizes to suit various processes
- Supports long-term, stable supply
Industrial Kiln Linings and Metallurgy
Lining castable and precast mix design
Kiln linings endure prolonged exposure to high temperatures and thermal shock; material gradation and purity determine service life. Mullite aggregates and fines enable optimized matrix gradation for castables, balancing workability with high-temperature performance.
- High-strength aggregates with customizable gradation.
- High aluminum content, designed for high-temperature applications
- Support for castable and precast formula supply
Ceramic
Ceramic Body and Kiln Furniture Formulation
Ceramic products are highly sensitive to raw material purity and firing shrinkage. Incorporating stable mullite powder and sand into the formulation helps control dimensional changes during firing.
- Controllable impurity content
- Fineness can be customized according to product requirements.
- Stable raw material sourcing for consistent long-term formulation.
