Outline of Research at the Start

This research aims to design and develop alumina-strengthened porcelain with high densification and low pyroplastic deformation so that the fine geometries porcelain with large, thin, and precise shape can be realized. The research will be performed as follows.
1) One-dimensional and/or high temperature expansion precursor for suppressing the sintering shrinkage;
2) high-temperature crystallization precursor for suppressing the bloating;
3) Fluxing agent for densifying the porcelain and tuning the viscosity.
