Fused Silica Powder
The material is high-quality fused sand crushed with a jet or vibration mill. Then it’s classified. Performance-wise, it is characterized by a low expansion, low stress and chemical corrosion resistance. Fused silicon has low Radioactivity, and good electrical radiation.
Where is fused silicon used in industry and why?
The silica powder, when mixed with the hydration material, can form a solid gel. It will also react with alkaline materials such as magnesium oxide, forming a gel. The following functions can be played by mortar, refractory castables and silica dust in cement-based concret:
Fused silica powder improves corrosion resistance.
2. The fused silicon has the ability to hold water, prevent bleeding and segregation. It also reduces the resistance when pumping concrete.
Concrete can be significantly improved by adding a layer of fused silicon powder.
The fusion of silicon powder can be used to reduce the dust that falls on concrete and castables sprayed and to increase the thickness.
Fused silicon powder has been used in C150 Concrete Engineering as a key component for high-strength, lightweight concrete.
Use of fused silicon powder in concrete or low-cement castables can improve durability and reduce costs.
7.Fused Silicon Powder can effectively prevent the concrete alkali-aggregate reaction.
Castable refractories can be made more compact by adding fused silicon powder. The mullite is formed more easily when Al2O3 and silicon coexist. This improves the high temperature strength of the material.
