6.一种如权利要求1-5任意一项所述的耐热高透光度天玉瓷的制备工艺,其特征在于,包括以下步骤:
S1:破碎球磨:称取既定量的高岭土、珍珠岩、白云石和菱镁矿采用破碎机进行破碎成碎块后,将碎块分别置入球磨机进行球磨,球磨后分别过筛,过筛后得到高岭土粉、珍珠岩粉、白云石粉和菱镁矿粉,将锆英砂和聚碳酸酯直接进行球磨后过筛,分别得到锆英砂粉料和聚碳酸酯粉料;
S2:原料混合:将S1中得到的各种粉料加入到预混机中,然后向预混机中依次加入氧化铝、硼酸、硝酸钾和助剂,启动预混机充分混合均匀,得到混合料A;
S3:成型、烘干:将混合料A与水按照一定的重量比例混合,持续搅拌20-30分钟制成泥饼,再将泥饼进行练泥,摞成柱状,然后拉胚成型,将成型胚体放置2-3天进行自然干燥,然后将自然干燥的成型胚体入窑中烘烤12-16小时后取出,烘烤温度为55-65℃,自然冷却6-10小时,得到素胚;
S4:上釉:将素胚加入常温水中浸泡30S后取出,待表面水淋干后,采用浸釉法在素胚内外上釉,再用喷釉法上二次瓷胎外釉;
S5:素烧:将上釉后的胚体加入窑内进行封闭式氧化烧,首先在400-1300℃的温度下烧制7-10小时,然后在1300℃的恒温下烧制1-2小时,最后自然冷却12-18小时即得到成品天玉瓷。
7.根据权利要求6所述的一种耐热高透光度天玉瓷的制备工艺,其特征在于:所述S1中高岭土粉、珍珠岩粉、白云石粉和菱镁矿粉的细度均不大于300目,所述锆英砂粉料和聚碳酸酯粉料的细度均不大于250目。
8.根据权利要求6所述的一种耐热高透光度天玉瓷的制备工艺,其特征在于:所述S5中,依次按照如下步骤进行烧制:在400-500℃的温度下烧制2-3小时;在500-800℃的温度下烧制2-3小时;在800-1000℃的温度下烧制1-2小时;在1000-1200℃的温度下烧制60-100分钟;在1200-1300℃的温度下烧制40-60分钟。
