Product internal performance index of the present invention: (1) folding strength can reach more than the 150Mpa, (2) thermostability: carry out a heat exchange through 220-20 ℃ of water and do not burst.
The present invention has the following advantages:
1, the internal performance that can make high silicon strengthen porcelain by the present invention has significant improvement, has solved the technical barrier that exists in the high siliceous reinforcement porcelain production effectively, is that the high silicon that is fit to suitability for industrialized production is strengthened porcelain.
2, because the quartz that quartz granularity is controlled at 10-15um in the base substrate accounts for 80-90%, and having added second and third disperse phase, it is carefully brilliant that it not only makes base substrate reach polycrystalline, and effectively suppress growing up of quartz particles, reduce stress riser, thereby reach the enhanced purpose.
