Abstract In this study, production of alumina and steatite containing ceramic insulators as thermostat material was realized by investigating the composition, pressing pressure and sintering temperature. 90 bar of pressing pressure was employed to give a ring shape to thermostat insulators by mixing with 3% kerosene. Alumina based samples were sintered at 1400°C, while 1300°C sintering temperature was determined to be efficient for steatite based samples. Optimum pressing pressure and sintering temperature for batches were 90 bar and 1350°C, respectively. Sintered bodies subjected to Megger test at 1200 V and 50 Hz exhibited good electrical insulation. It was concluded that higher alumina containing batch composition was the ultimate candidate as thermostat insulator, especially in terms of density and compressive strength. GRAPHICAL ABSTRACT

氧化铝和滑石基陶瓷绝缘子的生产和表征

摘要 本研究通过考察成分、压制压力和烧结温度，实现了作为恒温材料的氧化铝和滑石陶瓷绝缘子的生产。通过与 3% 煤油混合，使用 90 巴的压力使恒温器绝缘体形成环形。氧化铝基样品在 1400°C 下烧结，而 1300°C 烧结温度被确定为对滑石基样品有效。批次的最佳压制压力和烧结温度分别为 90 bar 和 1350°C。在 1200 V 和 50 Hz 下进行 Megger 测试的烧结体表现出良好的电绝缘性。得出的结论是，含有较高氧化铝的批料组合物是作为恒温绝缘体的最终候选者，尤其是在密度和抗压强度方面。图形概要
