摘要
根据K2 O -Na2 O -CaO -MgO -Al2 O3 -SiO2 系统结晶釉的组成和釉熔体结晶作用的特点 ,探讨不同组成和结构的钙镁矿物在该系统结晶釉中出现的可能性。认为橄榄石族、单斜辉石亚族、硅灰石族和黄长石均可能成为结晶釉的主要析晶相。各种矿物出现与否 ,和矿物晶体结构、熔体的氧硅比值、钙镁比例、碱性组成紧密相关。
Based on the characteristic of crystallization and chemical composition of silicate melt in K 2O-Na 2O-CaO-MgO-Al 2O 3-SiO 2 system,possibility of calcium-magnesium silicate minerals(with different component and structure)appeared in crystalline-glaze has been discussed by mineralogical theories.Minerals of olivine group,monopyroxene sub-group,wollastonite group or melilite group have been considered to be main crystallate of crystalline-glaze.It was thought that crystal classes of crystalline-glaze connected with melt's structure,O/Si ratio,CaO/MgO ratio and alkali content closely.
