Zirconia silica fume has a special use in the field of refractories , injection materials, ceramics and building materials.

Zirconia Silica Fume

Zirconia silica fume is a compound of zirconium dioxide, zirconium oxide melting products. 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 , injection materials, ceramics and building materials industries and high-strength concrete for its features of low impurities and good activity in refractory.

【Application】 Electronic materials, plastics, paint and coatings, silicone rubber, adhesives, high-grade;
