Patent ID: 7915187

Claim:
A method of producing a highly-pure fine titanium carbide powder comprising: highly-pure fine titanium carbide powder which includes a maximum particle size of 100 nm or less, said titanium powder including metals except titanium in an amount of 0.05 wt % or less and free carbon in an amount of 0.5 wt % or less; comprising the steps of; dissolving an organic compound serving as a carbon source in a solvent to prepare a liquid, said organic compound containing at least one OH or COOH group which is a functional group coordinatable to titanium of titanium alkoxide, and no element except C, H, N and O; mixing titanium alkoxide with said liquid to satisfy the following relation: 0.7≦α≦1.0 (wherein α is a molar ratio of said carbon source to said titanium alkoxide), so as to obtain a precursor solution; solidifying said precursor solution to obtain a product; and subjecting said product to a heat treatment in a vacuum atmosphere at a temperature of 1050 to 1500° C.
