Intrduction

Microsilica powder is also called silicon ash or condensed silica fume, or silica fume. It is the by-product of the process of ferrosilicon or silicon metal, which is made up of the high-purity quartz, coke and scrap iron in the furnace. The main components of the silica powder is SiO2. The color of the silica fume is grey.

Application in refractory

Microsilica in refractory is a highly effective pozzolanic material, the functions of adding microsilica are as follow:

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) Microstructure for gap filling

6) Rising the compact and intensity of refractory

7) Enhance elevated temperature strength and thermal shock of refractory.

8) Minimizes rebound loss
