A method of manufacturing a dense silicon carbide ceramic includes heat treating an alpha silicon powder in a vacuum to between 1200 DEG and 1400 DEG C., adding a boron powder either before or after heat treating, then, adding a substance containing carbon, milling the mixture, compressing the milled mixture into a desired shape, sintering the formed shape at 2100 DEG C. in an argon atmosphere. The method has particular application to manufacturing parts for gas turbines.
