摘　　要：采用ＳＥＭ、ＥＤＸ、ＸＲＤ 等手段，研究了ＫＮａＯ－ ＭｇＯ－ Ａｌ２Ｏ３ － Ｂ２Ｏ３ － ＳｉＯ２ 系全熔块乳浊釉的形成规律，指出釉层中均匀分布的大量ＭｇＳｉＯ３ 微晶是釉面乳浊的原因。组成中Ｂ２Ｏ３ 含量愈高，釉熔体的析晶倾向愈大。少量Ａｌ２Ｏ３ 则可以降低釉熔体高温粘度，抑制析晶，改善釉面白度和光泽度。在釉烧过程中，析晶继续进行，Ｂ２ Ｏ３ 含量的增加使基质釉玻璃的成熟温度降低。设计合理组成及快烧工艺，可得到釉面综合质量良好的微晶乳浊釉。The opacification formation rule of fritted glazes in KNaO-MgO-Al 2O 3-B 2O 3-SiO 2 system was investigated by means of SEM,EDX and XRD.It was pointed out that large amount of B 2O 3 MgSiO 3 microcrystal evenly dispersed in glaze layer resulted in opacification of glaze surface.The higher the amount of B 2O 3 in glaze flux was,the stronger tendency towards devitrification would become.A little Al 2O 3 would decrease high temperature viscosity of glaze flux, depress its devitrification and accordingly improve the whiteness and glossiness of glaze surface.During the firing process,crystallization continued.And increase of B 2O 3 made the maturing temperature of host glass decrease.By designing rational composition and fast firing process,we are able to obtain microcrystalline opaque glazes of good comprehensive quality.
