Yanshi City Guangming High-Tech Refractories Products Co., Ltd offers Mullite 70, a high-grade aluminosilicate refractory material with 68-73% Al2O3 and 22-25% SiO2 content. The material is engineered for extreme temperature resistance, maintaining structural integrity up to 1700°C, and is widely used in steelmaking, cement production, and glass furnace linings.
The fine-grain microstructure of Mullite 70 provides exceptional thermal shock resistance and low creep under load, making it ideal for kiln furniture, crucibles, and high-temperature insulation components. Its low thermal conductivity and high refractoriness under load (RUL) are standard for aluminosilicate refractories in this Al2O3 range.
This product is in demand across heavy industries in Asia, Europe, and the Middle East, particularly for applications requiring resistance to chemical corrosion and abrasion. Yanshi City Guangming High-Tech Refractories, based in Luoyang, Henan, supplies Mullite 70 for foundries, ceramics, and metallurgical plants where consistent performance at high temperatures is critical.

Verify the Al2O3 and SiO2 content with the supplier, as these percentages directly impact the material’s refractoriness and chemical resistance. Request a material test report to confirm the bulk density, porosity, and thermal conductivity, as these properties affect performance in high-temperature applications.
Clarify the Incoterms offered by Yanshi City Guangming High-Tech Refractories, as these will determine your responsibility for shipping, insurance, and customs. Lead times for refractory materials can be long due to specialized production, so confirm delivery schedules and port of loading in China.
Inspect the grain size, density, and surface finish of the delivered material, as variations can affect thermal shock resistance and mechanical strength. Ensure the supplier provides a certificate of compliance with ISO 2245 or other relevant standards, and conduct third-party testing if required by your industry regulations.
