Carbura de siliciu legat\u0103 cu nitrur\u0103 este un nou tip de material refractar avansat. Principalele sale produse includ tuburi de radia\u021bie din carbur\u0103 de siliciu legat\u0103 cu nitrur\u0103 de siliciu, c\u0103r\u0103mizi, rafturi din carbur\u0103 de siliciu legat\u0103 cu nitrur\u0103 \u0219i a\u0219a mai departe<\/p>\n

Performan\u021b\u0103 \u0219i utilizare<\/p>\n

1.nitrur\u0103 legat\u0103 sic, cu o textur\u0103 dur\u0103 \u0219i o duritate Mohs de aproximativ 9, sunt materiale de duritate \u00een materiale nemetalice, al doilea doar la diamant.<\/p>\n

2. Rezisten\u021ba \u0219i duritatea rafturilor de cuptor din carbur\u0103 de siliciu legat\u0103 cu nitrur\u0103 sunt ridicate la temperatura camerei. La 1200-1400 C, rezisten\u021ba \u0219i duritatea carburii de siliciu legate cu nitrur\u0103 sunt aproape la fel ca cele de la temperatura camerei pentru acela\u0219i timp. Cu utilizarea de atmosfere diferite, temperatura maxim\u0103 de utilizare \u00een condi\u021bii de siguran\u021b\u0103 poate ajunge la 1650-1750 C.<\/p>\n

3. Coeficientul de expansiune termic\u0103 al carburii de siliciu legate cu nitrur\u0103 de siliciu este mic. Comparativ cu carbura de siliciu \u0219i alte produse, conductivitatea termic\u0103 este mai mare. Nu este u\u0219or de produs stres termic. nitrur\u0103 legat\u0103 sic are o bun\u0103 stabilitate la \u0219ocuri termice \u0219i durat\u0103 lung\u0103 de via\u021b\u0103. Rezisten\u021b\u0103 la fluaj la temperaturi ridicate, rezisten\u021b\u0103 la coroziune, rezisten\u021b\u0103 la frig \u0219i c\u0103ldur\u0103 extreme, rezisten\u021b\u0103 la oxidare, u\u0219or de realizat produse cu precizie dimensional\u0103 ridicat\u0103 \u0219i care \u00eendeplinesc cerin\u021bele.<\/p>\n

4. nitrur\u0103 de siliciu carbur\u0103 de siliciu legate sunt utilizate pe scar\u0103 larg\u0103 \u00een fier \u0219i o\u021bel, metale neferoase, materiale de construc\u021bii chimice \u0219i alte industrii, economisirea energiei, protec\u021bia mediului, reducerea costurilor.<\/p>\n
