A chemical vapor composite process for producing high purity, fully dense refractory ceramics in complex geometric shapes. Preferred products are suitable for leading edge protection of very high speed space and air craft. The process is derivative of conventional chemical vapor deposition, but is able to create ceramic articles that are free of the residual stress normally associated with chemical vapor deposition. Parts and products produced have high purity, residual stress-free material of unlimited thickness in a great variety of geometries. Leading edge protective parts can be made much thicker than typical prior art ceramic parts so that the parts produced can assume load bearing function. And the parts provide much higher thermal conductivity than the prior are SiC covered carbon-carbon composite protective parts.
