摘　　要：本研究参照经验配方,采用正交实验设计等实验方法,利用扫描电镜等现代分析手段,通过合理选择原料,在配方中调整SiO2、Al_2O_3、K_2O、Na_2O之间的摩尔比,确定了一次烧成釉面砖坯釉的最佳配方,在烧成中采用“阶梯式升温”与快、缓升温结合,对釉面质量起到了促进作用。通过对坯体配方差热曲线、胀缩曲线的测试及扫描电镜分析,坯釉膨胀系数匹配,坯釉适应性好,而且釉面质量稳定,气孔、釉泡少,釉面光泽度高。In this research, optimum formulas for the body and glaze of once fast-fired glazed tile was obtained by making reference to their empirical recipes, conducting orthogonal experiments, using analytic instruments like SEM, rationalizing the choice of raw materials and adjusting the mol ratios of Al2O3, K2O and Na2O. The glazing quality was greatly improved after the firing process adopted a 'intensifying ladder' effectively combining slow fire and fast fire. The survey of DTA, ECA and SEM for the glazed tile's body and glaze revealed desired consistency in their thermal expansion coefficients, good mutual adaptability, well-controlled glazing quality with high glossiness and little blistering.
