Application of Feldspar in Synthesis of Leucite

Leucite has high thermal expansion coefficient, so the t hermal compatibility can be achieved between porcelain and metal. The frit conta ining leucite can be synthesized melting feldspar depending on annealed. The res ult showed that main crystal phase of frit was leucite. The thermal expansion co efficient of frit was 21.3×10 -6/℃。The frit is the foundation of improvi ng the thermal compatibility between porcelain and metal.
