METHOD FOR PRODUCING INGOT AND POWDER OF ZIRCONIUM CARBIDE
The present invention provides a method for producing an ingot of zirconium carbide at a low cost in an efficient manner. The present invention, specifically, provides a method for producing an ingot of zirconium carbide, characterized in that the ingot produced has a size of 50 mm or more, a density of 5.7 g/cm 3 or more, and a Vickers hardness of 1,500 or more, and that the method includes the steps of: (1) Step 1 of mixing zirconium oxide with carbon to obtain a mixture thereof, wherein the carbon is present in an amount of 15 to 20% by mass based on the zirconium oxide in the mixture; (2) Step 2 of forming the mixture into granules; (3) Step 3 of melting the granules using argon plasma; and (4) Step 4 of slowly cooling the melt to obtain the ingot of zirconium carbide.
