Alternatively, a silicon carbide body is obtd., silicon carbide powder of ave. grain size not more than 5 microns and contg. 0.1-5 wt.% magnesium boride and 0.1-5 wt.% carbon or an organic cpd. yielding that amt. by sintering at 1900-2300 deg.C in vacuum or an inert atmos. Pref. 50100 wt.% of the silicon cabride is the beta form, the balance being either the alpha or amorphous form. The magnesium boride may be formed in situ by adding separate boron and magnesium cpds. to the initial powder mixt.
