Zirconum White Microsilica Fume Powder for Refractories/Shotcrete/Concrete/Cement/Motar Industries
1. White Micro Silica Fume Introduction
White microsilica with SiO2 is up to 92%-96%; as a by-product of zirconia, it has excellent features both in silica and zirconia, such as high SiO2 content, fine granularity, large surface area and good fluidity to enhance the wear resistance, durability and reinforcement performance in the fields of injection materials, cement and concrete, refractory, ceramics and electronic materials.

6. Applications
Mainly used in unshaped refractory materials, construction, ceramics, pigments and chemical industrial, etc.
Used in the construction of cement concrete: which can reduce the dosage of cement concrete, eliminating material segregation and improve the concrete strength, enhance the wear resistance and durability, improve corrosion of steel, etc.
Used in monolithic refractories: which can effectively reduce the water addition, good thixotropy, and low temperature combination effect, is the ideal combination of agent, binder, additives and performance improvement of blending.
Used in the unsteady casting of ladle: which can be used for high temperature and steel water insulation.
Used in high alumina brick, magnesia brick, sliding water mouth brick, kiln and other high temperature equipment and other refractory materials: which can improve the products quality grade, acting as other ordinary refractory materials.
