| titleOfInvention | Method of producing sealed articles from heat resistant composites |
| abstract | FIELD: process engineering. n SUBSTANCE: invention relates to production of sealed articles for chemical industry and metallurgy. First, carcass of refractory fibre is made that features linear expansion factor approximating to that of the matrix material components. Then, carcass is compacted by carbon-bearing material to get the billet of porous carbon-bearing composite impregnated with ceramics-forming binder that makes a precursor of silicon nitride and/or carbide. Plastic billet is formed at binder solidification temperature and processed at its final temperature of 1300-1600°C. Then, carbon is introduced in material pores. Then, siliconising is performed by vapour-liquid-phase process at heating, holding and cooling in silicon vapours. For this capillary condensation of silicon vapours is conducted at 1300-1600°C and reactor pressure not over 36 mmHg followed by holding at 1600-1700°C for 1-2 hours. Finished article finished is cooled and withdrawn from the unit. n EFFECT: longer life. n 4 cl, 1 tbl, 11 ex |
