ABSTRACT:
A composite material crucible for a device for making single crystals having a single layer integrally-formed cylindrical wall made of composite materials in order to simultaneously provide mechanical strength and matching of its thermal conductivity to the thermal conductivity of a molten sample. The wall has an inner lining intimately and integrally bonded thereto for providing the functions of sealing and physical and chemical compatibility with the sample, without contamination thereof. A method for manufacturing the cylindrical crucible comprising selecting a composite material wall composition including fibers made of carbon or silicon carbide, and a matrix made of carbon or silicon carbide, making from the composite material a single layer integrally-formed cylindrical wall, and depositing on the cylindrical wall an optimized material to form an inner coating which is intimately and integrally bonded to the cylindrical wall.
