FIELD: power engineering.
SUBSTANCE: method to manufacture a ceramic tube for a fuel element shell, made of silicon carbide layers, includes stages: tubular frame is formed from fibre with structure β-SiC, its impregnation is carried out by a ceramic-forming precursor in inert gas atmosphere, subsequent stepped thermal treatment to produce a ceramic matrix and formation of ceramic composite in process of final heat-temperature thermal processing.
EFFECT: elimination of one of main faults of ceramic products - brittleness, provision of environmental purity of the method.
