Beschreibung
Zusammenfassung:	Disclosed is a process for producing a RBSiC member that has a large size and a complicated shape and possesses ceramic properties. The process is a Selective Laser Sintering process which includes providing a raw material containing silicon carbide particles and a binder, forming a thin layer of the raw material, and sintering the thin layer by irradiating a desired area in the thin layer with laser to form a sintered thin layer, repeating the step of forming the sintered thin layer to obtain a green body, impregnating the green body with a carbon source and curing the green body impregnated with the carbon source to give a cured body, carbonizing an organic compound component in the cured body to give a fired body, infiltrating the fired body with silicon, and subjecting the fired body to reaction sintering to give a RBSiC member, wherein the fired body contains 8% to 30% by weight of carbon.
