Carbide reduction of yttrium oxide in a vacuum (Y/sub 2/O/sub 3/ + 5C = 2YC + 3CO) was utilized in preparing YC. The YC forms at 1900 deg C. The microhardness of the YC is 120 kg/ mm/sup 2/, melting point 1950 plus or minus 20 deg ,specific resistivity 4 x 10/sup 4/ mu omicron - cm, electromotive force 34.8 mu v/C deg , and the coefficient of thermal expansion is 1.36 x 10/ sup -1//C deg . The chemical stability was tested in various media. (R.V.J.)
