Title:
METHOD FOR PREPARING NANOMETER MAX PHASE CERAMIC POWDER OR SLURRY HAVING LAMINATED STRUCTURE BY MEANS OF BALL MILLING AND REGULATING OXYGEN CONTENT OF POWDER
Document Type and Number:
WIPO Patent Application WO/2020/042948
Kind Code:
A1
Abstract:
A method for preparing nanometer MAX phase ceramic powder or slurry having a laminated structure by means of ball milling and regulating the oxygen content of the powder. Micron-sized MAX phase ceramic coarse powder is adopted as a raw material, during ball milling, a gas or a liquid-state gas having a special effect is introduced into a ball milling tank, and by means of multi-dimensional functions and regulation such as ball milling parameters and gas reaction, the nanometer laminated MAX phase ceramic powder or the slurry containing the component is obtained. The surface components and the activated state of the powder are regulated while the particle size adjustment control of the powder is realized.
