Abstract
A process for the fabrication of a SiC-based article that includes preparing an aqueous suspension with SiC powder, a titanium source, a carbon source and boron carbide powder, spray drying the mixture to obtain a powder, preparing a green body from the powder, applying heat treatment to the green body in a pyrolysis/thermolysis step, pressureless sintering the green body, optimally followed by HIPing for further densification.
