Product Advantages
1. Excellent High Temperature Resistance

Our mullite sand and powder have outstanding high-temperature performance, with a refractoriness of 1770-2000℃. The material can maintain excellent mechanical strength and chemical stability under high-temperature environments, making it an ideal choice for refractory applications.

The high temperature resistance of mullite refractory material helps improve the service life and reliability of refractory products, reducing damage caused by thermal stress and temperature fluctuations.

2. Superior Thermal Shock Resistance

One of the key advantages of mullite sand is its excellent thermal shock resistance. The unique crystal structure of mullite allows the material to withstand repeated heating and cooling cycles while maintaining structural integrity.

This feature makes mullite powder and mullite sand widely used in kiln furniture, furnace linings, precision casting molds, and other applications where rapid temperature changes frequently occur.

3. Low Thermal Expansion Performance

Our mullite refractory material has a low thermal expansion coefficient, which helps reduce cracking and deformation during high-temperature operations.

The stable expansion characteristics of mullite sand and powder make them especially suitable for precision applications requiring dimensional accuracy, such as investment casting and advanced ceramic production.

4. High Purity and Stable Chemical Properties

The selected raw materials and advanced processing technology ensure that our mullite sand and mullite powder have stable chemical composition and excellent purity.

The material provides good resistance to chemical corrosion and can maintain performance when exposed to high-temperature environments, molten materials, and industrial gases.

5. Multiple Particle Sizes Available

We offer mullite sand and powder with different particle sizes ranging from 10 mesh to 200 mesh. Various sizes can meet different application needs:

Coarse mullite sand for refractory aggregates
Medium particle mullite sand for casting materials
Fine mullite powder for ceramic and precision applications

Customized mesh sizes are also available according to customer specifications.
