ABSTRACT:
A reaction-sintered silicon carbide body having portions differing from each other in free silicon content and such a body with a surface layer rendered more readily abradable than the remainder of the body by the removal of free silicon from the surface layer. It has a particular application in the provision of shrouds for gas turbines, which can be produced by slip-casting in two stages.
