Lithium Chinastone is a kind of rocky mineral, formed by Quartz, sericite and spodumene with density 2.7~3.0 and hardness 4~7. It can be used directly as a main body material. Followings are its main features:
The low coefficient of linear expansion can be formed within the relatively wide range of compositions of body materials.
It can reduce the rate of body damage, as a result of the reduced occurrence of cracking.
It can improve the product quality by shortening the cooling down time in biscuit firing.
It reduces the firing temperature without¡¡shortening the firing range,. It can also reduce the firing temperature. It could be much better if using with feldspar and nepheline syenite.
It reduces the viscosity of ceramic glaze at high temperature, increases the glaze flow , improves the glaze gloss , reduces the softening temperature and fusing temperature .
It improves body thermal stability and can be used as mineralizer in ceramic forming process.
