Abstract
An object constructed of silicon carbide is made up of a plurality of sintered silicon carbide component parts in simple solid forms. This approach allows the production of objects having configurations that are obtainable only with difficulty or not at all by prior art approaches. The component parts are inseparably connected together by means of a silicon carbide film integrally formed on said component parts by chemical vapor deposition. In order to provide substantially improved joint strength and overall structural strength, the silicon carbide film preferably has a crystal structure in which the X-ray diffraction intensity ratio of each crystal face to the (111) face is 0.1 to 10 and/or in which the aspect ratio of crystal grains is 1 to 30.
