Ceramic sintering method and ceramic part manufactured by adopting ceramic sintering method
The embodiment of the invention provides a ceramic sintering method and a ceramic piece manufactured by adopting the ceramic sintering method. The ceramic sintering method comprises the following steps: placing a ceramic green body on a setter plate; the ceramic green body is subjected to temperature rise stage sintering, the temperature rise stage comprises a plurality of temperature rise time periods, and at least one temperature rise time period comprises a temperature rise sub-time period and a first temperature adjustment sub-time period; the heating rate of the first temperature adjustment sub-period is smaller than that of the heating sub-period; the ceramic green body is sintered in a cooling stage, the cooling stage comprises a plurality of cooling time periods, and at least one cooling time period comprises a cooling sub-time period and a second temperature adjusting sub-time period; the cooling rate of the second temperature adjusting sub-period is smaller than that of the cooling sub-period. According to the ceramic sintering method and the ceramic part manufactured by adopting the ceramic sintering method, the tensile strength of the ceramic part can be improved, the porosity is reduced, and the residual stress is reduced, so that the surface defects of the ceramic part can be reduced, and the processing property of the ceramic part is improved.
本发明实施例提供一种陶瓷烧结方法及采用该陶瓷烧结方法制成的陶瓷件，该陶瓷烧结方法包括：将陶瓷生胚放置于承烧板上；对所述陶瓷生胚进行升温阶段烧结，且升温阶段包括多个升温时段，至少一个升温时段包括升温子时段和第一调温子时段；第一调温子时段的升温速率小于升温子时段的升温速率；对陶瓷生胚进行降温阶段烧结，且降温阶段包括多个降温时段，至少一个降温时段包括降温子时段和第二调温子时段；第二调温子时段的降温速率小于降温子时段的降温速率。本发明实施例提供的陶瓷烧结方法及采用该陶瓷烧结方法制成的陶瓷件，可以提高陶瓷件的抗张强度、降低气孔率和减小残余应力，从而可以减少陶瓷件的表面缺陷，提高陶瓷件的工艺性能。
