摘　　要：以高岭土、方解石、氧化铝为主要原料,使用长石和骨碳为助熔剂制备得到钙质日用瓷。研究了骨碳及其添加量对钙质日用瓷物相组成、烧结性能以及透光性能的影响。结果表明:骨碳可有效促进试样烧结,提高试样抗弯强度,增加试样透光性。当骨碳添加量为4 wt%时,试样综合性能最优。试样主晶相为钙长石,同时含有少量β-磷酸三钙,试样抗弯强度为103 MPa,吸水率为0.18%,体积密度为2.24 g/cm^(3),透光性能良好。Calcium-based household porcelain was prepared using kaolin,calcite,and alumina as the main raw materials and feldspar and bone ash as fluxing agents.The influence of bone ash and its addition amount on the phase composition,sintering performance,and translucency of the calcium-based household porcelain was investigated.The results showed that bone ash could effectively promote the sintering of samples,enhance the flexural strength of samples,and increase their translucency.When the addition amount of bone ash is 4 wt%,the comprehensive performance of the samples is optimal.The main crystal phase of the samples is anorthite,with a small amount ofβ-tricalcium phosphate.The flexural strength of the samples is 103 MPa,the water absorption rate is 0.18%,the bulk density is 2.24 g/cm^(3),and the translucency is good.
