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;
