METHOD FOR SYNTHESIZING HIGH-PURITY ULTRAFINE ZRC-SIC COMPOSITE POWDER

摘要

A method for synthesizing high-purity ultrafine ZrC-SiC composite powder. The high-purity ultrafine ZrC-SiC composite powder is prepared by using zirconium silicate only or zirconium silicate with one or both of zirconia or silica sol as a zirconium source and a silicon source materials, using sucrose or glucose as a carbon source material, and using acrylamide monomer and methylene bis-acrylamide cross-linking agent as a gel material.
