摘要: 本文以海南紫金陶泥、锂辉石、锂白石、煅烧滑石、高岭土为原料,通过改变煅烧滑石与高岭土的含量优化配方组成,调节样品的热膨胀系数,制备低膨胀耐热紫砂陶,并通过热膨胀系数和抗折强度表征其抗热震性的变化。结果表明,当紫金陶泥含量为32.8%(质量分数)、锂辉石含量为32.8%(质量分数)、锂白石含量为9.4%(质量分数)、煅烧滑石含量为10.0%(质量分数)、高岭土含量为15.0%(质量分数)时,原料经过9 h的球磨并在1 150 ℃下保温60 min所制得的紫砂陶样品热膨胀系数最低(1.32×10-6-1),吸水率为0.25%,抗折强度为83.89 MPa。

Abstract: In this study, the Hainan Zijin clay, spodumene, lithium white stone, burnt talc and kaolin were used as raw materials. The formula composition was optimized by changing the content of burnt talc and kaolin, and the coefficient of thermal expansion of sample was adjusted to prepare low-expansion and heat-resistant purple clay pottery. The change of thermal shock resistance was characterized by coefficient of thermal expansion and flexural strength. The results show that when the content of Zijin clay is 32.8% (mass fraction), the content of spodumene is 32.8% (mass fraction), the content of lithium white stone is 9.4% (mass fraction), the content of burnt talc is 10.0% (mass fraction), and the content of kaolin is 15.0% (mass fraction), the coefficient of thermal expansion of purple clay pottery sample prepared by raw material ball milling for 9 h and holding at 1 150 ℃ for 60 min is the lowest (1.32×10-6-1), the water absorption rate is 0.25%, and the flexural strength is 83.89 MPa.

Key words: Hainan Zijin clay, spodumene, β-spodumene solid solution, coefficient of thermal expansion, flexural strength
