Zirconia silica fume/Zr Silica Fume

 

Zirconia silica ,  a compound of zirconium dioxide, zirconium oxide melting products, also called silicon ash, the production of silicon-zirconium off special device which used to collect the silica powder, not only has the general characteristics of sillca , but also  a certain amount of zirconia powder. Zirconia silica has a special use in the field of refractories ,  buming injection materials, ceramics and building materials industries and high-strength concrete for its features of low impurities and good activity in refractory.
