Preparation method of pressureless sintering micro-nano mixed silicon carbide granulated powder
The invention discloses a preparation method of pressureless sintering micro-nano mixed silicon carbide granulation powder, and relates to a preparation method of silicon carbide granulation powder. The method mainly solves the problems that silicon carbide nanoparticles are introduced in the existing granulation process to toughen silicon carbide ceramic, the nanoparticles are easy to agglomerateand combine, and uniform dispersion cannot be achieved. The preparation method comprises the following steps: 1, powder pretreatment; 2, high-energy treatment; 3, dispersing the nano powder; 4, dispersing the micron powder; 5, mixing the slurry; and 6, spray granulation. The method is used for preparing the pressureless sintering micro-nano mixed silicon carbide granulation powder.
