Application:
High quality silica fume is mainly used as high performance refractory castable, preformed unit, ladle material, breathable brick, self flow refractory castable and dry wet jet material.
In the field of high temperature ceramics, such as: silicon carbide products with high temperature oxide, lightweight calcium silicate insulation material, corundum mullite electromagnetic kiln, high-temperature wear-resistant materials and products, corundum and ceramic products, dragon products, the use of micro silica fume has high mobility, low storage capacity, high density and high intensity characteristics and so on.
