Refractory Microsilica Introduction

The use of Micro silica powder in refractory castables provides better particle packing. It allows for less water to be used while maintaining the same flow characteristics. It also promotes low temperature sintering and the formation of mullite in the matrix of the castable. This produces a castable that has a low permeability to avoid gas, slag and metal penetration. Castables incorporating microsilica powder are stronger than non-microsilica powder containing castables especially at high temperatures with higher density they attain lower porosity and are more volume stable

Features Characteristics for Refractory microsilica powder

1. Enhancing the fluid of pouring refractory.
2. Reducing the volume of used water.
3. be easy to shape.
4. Raising the production efficiency.
5. Raising the compact and intensity of refractory.
6. Enhance elevated temperature strength and thermal shock of refractory.
