Abstract: Ten glaze property figures of D₁₁、 D₁₂、D₁₃、D₁₄、D₁₅、D₂₁、D₂₂、D₂₃、 D₂₄, D₂₅ in pyroxene-type glaze of NKMCAS system were investigated by OM、 TEM and XRD. Effects of temperatures and mole compositions (including K₂0+Na₂0、 MgO、 CaO、 Al₂O₃、 Si0₂) upon glaze appearance and glaze microstructure were analyzed. Regular changes with chemical compositions in these glaze formulae were revealed.

Keywords: pyroxene-type glaze, crystallization, phase separation
