摘　　要：通过合理调配CaF_2和CaO的加入量,在1120℃温度下制备出了具有较好光泽度的透明无铅硼釉及较好白度的硼乳浊釉。用单因素法探讨了CaO和CaF_2含量对低温无铅硼釉釉面透明度(乳浊度)、光泽度、流动性的影响。结果表明,CaO可以抑制无铅硼釉的分相,降低釉的乳浊度,提高透明度,增加流动性,但含量多时会降低釉的光泽度。CaF_2比CaO具有更强的助熔作用,可以使石英充分熔融,但同时由于釉粘度的降低,会析出钙长石和硅灰石晶体,降低釉的透明度。By reasonably allocating the amount of CaF2and CaO,the lead-free transparent glaze with better glossiness and boron opalescent glaze with better whiteness were prepared at1120.The effect ofCaO and CaF2content on transparency(opacity),glossiness and fluidity of lead-free boron glaze was discussed by single factor method.The results show that CaO can increase the transparency and fluidity of the glaze because the phase separation is isuppress,but the excess CaO addition reduce the glossiness of the glaze.CaF2has stronger fluxing effect than CaO,which can make the quartz melt fully.But at the same time,because of the decrease of glaze viscosity,calcium feldspar and wollastonite crystals will be precipitated and the transparency of the glaze will be reduced.
