摘　　要：首次成功烧制出温度低于800℃的透明釉。通过XRD和SEM表征对釉料烧成过程降温速率进行了初步探讨,结果表明,釉熔体玻璃化转变温度至釉料始熔温度之间,降温速率为15～25℃/min,釉面透明度较好,析晶少;低于釉料始熔温度,降温速率为5～10℃/min,釉面受热均匀,不易出现裂纹。Here, a glaze with a melting temperature below 800℃ was obtained. The cooling technics in calcined process was discussed by XRD and SEM characterazition, and the result show that, between the vitrification point and the initial melting temperature of galze, when the cooling rate is 15 - 25℃ /min, glazes with little recrystallization and good transparency can be obtained below the initial melting temperature ,when the cooling rate is 5 - 10℃ /min, the glazes was heated equably and with little crack.
