As a new raw material, silica fume is widely used in the refractory industry. It plays an important role in the improvement of monolithic refractories.
Practical applications of silica fume in the following areas:
1. Replace pure aluminum niobium oxide as refractory material.
2. As an additive to produce unshaped and shaped refractory products, its strength and high temperature performance are greatly improved.
3. As a pouring and coagulation accelerator for the steel drum as a whole.
4. Cohesive agents, binders, coagulants, and additives for other refractory products.
