1.Improve refractory materal's liquidity
2.Reduce the usage of water
3.Easy to shape
4.Improve the efficiecny

Micro silica esd in refractory is a highly effective pozzolanic material, the functions of adding micro silica is as follows,

1.Enhancing the liquidity of pouring refractory

2.Reducing the usage of water

3.To be easy to shape

4.For gap fillinf effect

5.Improve the compact and intensity of refractory

6.Improve the efficiency of producing

7.Enhacing elevated temperature strength and the thermal shock of refractory minimizes rebound loss

The specification of micro silica used in refractory is as below,
