Fused Mullite Powder For Foundry Coatings
Fused Mullite Powder is typically packed in sturdy, moisture-proof bags made of polyethylene or paper. The bags are designed to protect the powder from moisture and other environmental factors that could affect its properties. The size of the bags can vary depending on the intended use of the powder.
Descripció
Description
Fused mullite powder is commonly used in foundry coatings due to its high-temperature resistance, chemical inertness, and excellent physical properties. Foundry coatings are applied to molds and cores to improve their surface finish, reduce defects, and protect them from thermal shock during metal casting.
Fused mullite powder is made by fusing high-purity alumina and silica at high temperatures, resulting in a material that is highly resistant to thermal shock, corrosion, and erosion. The powder has a uniform particle size distribution and a high packing density, which ensures consistent coating thickness and coverage.

Benefits
High-temperature resistance: Fused mullite powder can withstand high temperatures without losing its physical or chemical properties, making it ideal for use in foundry coatings for high-temperature casting applications.
Chemical inertness: Fused mullite powder is chemically inert and does not react with other materials, which helps to prevent contamination and ensure the quality of the casting.
Low thermal expansion: Fused mullite powder has a low coefficient of thermal expansion, which means that it can withstand thermal shock and stress without cracking or breaking.
Excellent physical properties: Fused mullite powder has excellent mechanical properties, including high strength and hardness, which can help to improve the durability and performance of the coating.
