High-density fine-grain ceramic as well as preparation method and application thereof
The invention relates to high-density fine-grain ceramic as well as a preparation method and an application thereof. The preparation method of the high-density fine-grain ceramic comprises the following steps for sintering a ceramic biscuit: carrying out steps of heating, heat preservation and cooling on the ceramic biscuit for n times, wherein n is a natural number greater than or equal to 2; the relative density of the high-density fine-grain ceramic is larger than or equal to 99%, and the grain size is smaller than or equal to 10 micrometers. The technical problem to be solved is how to prepare the high-density fine-grain ceramic, so that the relative density of the ceramic is greater than or equal to 99%, and the grain size is less than or equal to 10 microns. Meanwhile, the method can complete ceramic sintering by using equipment in the prior art, special equipment is not needed, the production cost is low, and large-scale production and industrial popularization are easy, so that the method is more practical.
本发明是关于一种高致密细晶粒陶瓷及其制备方法和应用。所述高致密细晶粒陶瓷的制备方法按照以下步骤烧结陶瓷素坯：将所述陶瓷素坯进行n次“升温，保温和降温”，其中，n为大于或者等于2的自然数；所述高致密细晶粒陶瓷的相对密度≥99％，晶粒尺寸≤10μm。所要解决的技术问题是如何制备一种高致密细晶粒的陶瓷，使所述陶瓷的相对密度≥99％，晶粒尺寸≤10μm；同时，所述方法使用现有技术中的设备即可完成陶瓷烧结，无需引入特殊设备，生产成本低，易于大批量生产和工业化推广，从而更加适于实用。
