摘要: 以方解石、高岭土、氧化铝等为主要原料,长石、烧滑石和白云石作为助熔剂制备钙长石质日用瓷,探究不同助熔剂及其用量对钙长石质日用瓷性能的影响。结果表明,当单一长石作为助熔剂时,其助熔效果较差,且长石添加量过多会导致试样抗弯强度显著降低。当烧滑石与长石复合作为助熔剂时,烧滑石添加量较少时助熔效果不明显;当烧滑石添加量提高至4%(质量分数)时,试样吸水率显著降低,抗弯强度明显提高。当白云石和长石复合作为助熔剂时助熔效果较好,且随着白云石添加量的提高,试样抗弯强度先增大后减小,当添加量为6%(质量分数)时试样综合性能较优,其吸水率为0.27%,抗弯强度为101 MPa,同时具有良好的透光性。

Abstract: Anorthite-based daily porcelain was prepared by using calcite, kaolin and alumina as the main raw materials, feldspar, burnt talc and dolomite as fluxes. The effects of different fluxes and their addition amounts on properties of anorthite-based daily porcelain were studied. The results show that the fluxing effect is poor when feldspar is served as single flux. At the same time, excessive feldspar will lead to the significantly reduction of bending strength. With burnt talc and feldspar as composite fluxes, the fluxing effect is not obvious at a low addition amount of burnt talc. When the addition amount of burnt talc increases to 4%(mass fraction), the water absorption of sample obviously decreases and the bending strength is improved dramatically. The fluxing effect is good when the dolomite and feldspar are served as composite fluxes. With the increase of the addition amount of dolomite, the bending strength of sample increases first and then decreases. When the addition amount of dolomite is 6%(mass fraction), sample has the best comprehensive properties, which has a water absorption of 0.27%, bending strength of 101 MPa and good transparency.
