Refractory Raw Material

Refractory raw materials refer to the materials necessary for the production of refractory products, which is the basis for the production of refractory materials. Refractory raw materials are mostly natural minerals. With the continuous improvement of the requirements for the comprehensive performance of refractories, industrial raw materials and synthetic raw materials (such as industrial alumina, synthetic mullite, artificial refractory fiber, artificial refractory hollow ball, etc.) are increasingly used in the production of refractories. The quality and cost of refractory products largely depend on the correct selection and reasonable use of raw materials.

Refractory raw materials can be divided into acidic refractory raw materials, basic refractory raw materials and neutral refractory raw materials according to their chemical properties; They can be divided into natural mineral raw materials and synthetic raw materials according to their sources; Generally, the raw materials for producing refractory materials are divided into main raw materials and auxiliary raw materials.
