In the world of high-temperature industries, the quality of your raw materials defines the excellence of your final product. Today, we are diving deep into our Fused Silica A Grade (4-10 Mesh)—a premium material engineered for stability, purity, and performance in the most demanding environments.
Fused silica is produced by melting high-purity silica sand in electric arc furnaces at temperatures exceeding 1760°C. Our A Grade classification signifies the highest tier of purity, characterized by:
Ultra-low thermal expansion coefficient, ensuring dimensional stability during rapid temperature changes.
High chemical purity, with SiO2 content typically exceeding 99.9%.
Excellent electrical insulation and low thermal conductivity.
The Advantages of 4-10 Mesh Size
The 4-10 Mesh specification refers to the particle size (ranging approximately from 2.0mm to 4.75mm). This specific grain size is ideal for:
Refractory Castables: Providing a robust skeleton for high-temperature linings.
Investment Casting: Acting as a high-quality stucco material to prevent mold cracking.
Technical Ceramics: Ensuring precise structural integrity in finished parts.
