Title:
SILICON CARBIDE POWDER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/212414
Kind Code:
A1
Abstract:
The present invention relates to a preparation method for ultra-pure silicon carbide using a superporous spherical silica aerogel as a silica raw material, wherein the method having effects of enabling the low-temperature synthesis of silicon carbide by increasing a reaction area with a carbon raw material, producing ultra-pure silicon carbide by uniformly adjusting the size and shape of a silicon carbide powder, and improving the economic efficiency and productivity in the synthesis of silicon carbide by using low-priced water glass to prepare the silica aerogel particles, and therefore, it is expected that the silicon carbide powder prepared by the preparation method of the present invention can be provided as a raw material optimized for the preparation of silicon carbide sintered bodies and single crystal ingots.
