Claim Text:
1. A process for fabrication of a SiC-based article, comprising: preparing an aqueous suspension of SiC powder with a first amount of water soluble titanium compound that is convertible to TiO drying the aqueous suspension to obtain a powder mass containing the boron carbide and SiC particles coated with the binder, the titanium compound and the carbon source; preparing a green body from said powder mass; thermally decomposing said titanium compound and said carbon source coating the boron carbide and the SiC particles in said green body to convert said titanium compound to titanium dioxide and to covert the carbon source to carbon; while pressureless sintering said green body, reacting the titanium dioxide, the carbon and the boron carbide to obtain titanium diboride and carbon monoxide gas after said thermally decomposing step to obtain a pressureless sintered body; thereby extracting carbon from said green body while pressureless sintering said green body.
