Method for preparing fine-grain ceramic by using cold sintering-flash sintering technology through duplex process
The invention relates to a method for preparing fine-grain ceramic by a two-coupling method based on a cold sintering-flash sintering technology, which comprises the following steps: mixing fine-grain ceramic raw material powder into a mixed raw material, carrying out compression molding, firstly carrying out cold sintering to prepare a sample, and then carrying out flash sintering on the sample. The compact fine-grain ceramic can be prepared at a low temperature within a short time, the problem that the density and grain size distribution of a flash sintering sample have obvious non-uniform characteristics is solved, and a brand-new method is provided for preparation of a fine-grain ceramic material.
本发明涉及一种冷烧结‑闪烧技术的两联法细晶陶瓷制备方法，包括：将细晶陶瓷原料粉末混合为混合原料并压制成型，先进行冷烧结制得样品，再对样品进行闪烧。可以在较低温度和较短时间内制备致密的细晶陶瓷，且改善了闪烧样品的密度和晶粒尺寸分布存在明显的非均匀特征的问题，为细晶陶瓷材料的制备提供了一种全新的方法。
