What are the conditions for mullite stone?

When the mullite stone is used, it must have the following important conditions:

1, there is considerable intensity;

2, can withstand considerable high temperature;

3, in the high temperature, there is no narrowness, perhaps the narrowness is very small;

4, there is no load softening at high temperature, perhaps the weight of the softening is minimal;

5, can counter the sudden change in temperature;

6, thermal conductivity. When the billet (ie, the blank into the mullite stone), first spread a thin layer of rice ash on the bottom of the mullite stone, perhaps high-alumina clay, or quartz powder The embankment billets are sintered together with the crucible. Generally, the slag cake is settled under the billet, in particular, the color of the glazed billet which has a high fluidity also has a sticky handle, and a soft slag cake is added to prevent the glaze from flowing into the crucible
