FIELD: construction industry. n SUBSTANCE: manufacturing method of composite material on the basis of β-SiC, which involves: a) obtaining the mixture called "mixture-predecessor", which contains at least one predecessor β-SiC and at least one carbon-bearing heat-curable resin, b) forming the above mixture- predecessor in the form of granules, plates, tubes or bricks for manufacturing intermediate product, c) resin polymerisation, d) introduction of the above intermediate products to the capacity, e) closing the above capacity by means of the closing device allowing to avoid gas pressure increase, f) heat treatment of the above intermediate products at temperature of 1100°-1500°C for removing organic resin components and forming β-SiC in the end product. Products manufactured with the above method can be used as inner lining of electrolysis bath of fused salt or inner lining of incinerator. n EFFECT: manufacturing products in air atmosphere at normal pressure without deteriorating their quality. n 17 cl, 8 ex |
