Zirconia White Micro Silica Fume Powder for Refractories/Shotcrete/Concrete/Cement/Motar
1. White Micro Silica Fume Introduction
Zirconium silica fume, a compound of zirconium dioxide, zirconium oxide melting products, also called silicon ash. This Zr silica fume is derived from the same zircon used to make fused Zirconia, and is captured from the furnace during the fusion process. It not only has the general characteristics of silica, but also has a certain amount of zirconia powder. It is amorphouse, gray-white flour and characterized by a particle size less than 1 micron and high specific surface area which makes it a particularly high quality product.

Application of White Microsilica
1. widely used in casting refractories ,fused and sintered refractories. Such as high performance and low cement refractory materials and prefabricated parts, large iron hooks and steel materials, ventilation tiles, apply mending materials, etc. gravity-based refractory materials and construction of dry and wet spray application; oxide silicon carbide products(ceramics kiln with, every flame plate, etc.);Lightweight high temperature calcium silicate insulation material; Electric kilns with corundum mullite puser; high-temperature resistant materials and products; corundum and ceramic products.
2.New wall materials, decorative materials, wall thermal insulation mortar, insulation mortar, interface agents.
3.Nano-silica sol, as active material for advanced environmental protection coating, fire protection and anti-corrosion coatings.
4.For mortar and concrete in : high-rise buildings, the harbor docks, dams, water culvert, railway public bridges, subways, tunnels, airport runways, concrete pavement and the coal mine tunnel shotcrete reinforcement.
5.In rubber, resin, paint, unsaturated polyester reinforced polymer materials used as fill material..
6.Powder processing on the surface of the wall of the building.
7.Additives of other active areas.
