R\u00e4nikarbiidipulbrit tuntakse ka nimetusega \u201eemer\u00fc\u00fc\u201c, tooted on kuusnurksed kristallid, suhteline tihedus 3,20\u20133,25, Mohsi k\u00f5vadus 9,2, mikrok\u00f5vadus 2840\u20133320 kg\/mm\u00b2. R\u00e4nikarbiidil on stabiilsed keemilised omadused, k\u00f5rge soojusjuhtivus, v\u00e4ike soojuspaisumistegur ja hea kulumiskindlus. R\u00e4nikarbiidipulbril on palju olulisi rakendusvaldkondi, nagu funktsionaalne keraamika, konstruktsioonikeraamika, k\u00f5rgtehnoloogilised tulekindlad materjalid, abrasiivid, metallurgia jne.<\/p>\n

(1) Abrasiiv<\/p>\n

R\u00e4nikarbiidipulbrit saab kasutada lihvimisvahendina v\u00f5i lihvimise abimaterjalina klaasi, kvartskristalli, prisma-kristalli, keraamika, kivi, malmi ja m\u00f5nede v\u00e4rviliste metallide, karbiidist, titaanisulamite, kiirterasest l\u00f5ikeriistade lihvketaste jms lihvimiseks ja t\u00f6\u00f6tlemiseks.<\/p>\n

(2) Metallurgilised ja k\u00f5rgtemperatuursed tulekindlad materjalid<\/p>\n

R\u00e4nikarbiidist deoksidaatori ja vahtkeraamiliste filtrite rakendused terasetehastes; r\u00e4nikarbiidist vahtkeraamilised filtrid, millel on suurep\u00e4rane tugevus, vastupidavus k\u00f5rgetele temperatuuridele ja keemilisele korrosioonile.Kasutustemperatuur \u00fcle 1380 Celsiuse kraadi; neid kasutatakse laialdaselt sulametalli filtreerimisel, k\u00f5rgtemperatuursete heitgaaside t\u00f6\u00f6tlemisel, katal\u00fcsaatorikandjates, tahkistes soojusvahetites, spetsiaalsetes t\u00e4iteainetes ja muudes valdkondades.<\/p>\n

(3) Struktuurilised\/funktsionaalsed keraamilised materjalid (reaktsioonpaagutamine\/surveta paagutamine)<\/p>\n

Ideaalne materjal r\u00e4nikarbiidi valmistamiseks, n\u00e4iteks kulumiskindlate torude, tiivikute, pumbakambrite, ts\u00fcklonite ja maagikoppide vooderdiste tootmiseks, mille kulumiskindlus ja kasutusiga on 5\u201320 korda suurem kui malmil v\u00f5i kummil, kuid samuti \u00fcks ideaalsemaid materjale lennuv\u00e4ljade rajal.Surveta paagutatud r\u00e4nikarbiidi saab kasutada kuulikindlate keraamiliste plaatide, keraamiliste lehtede ja keraamiliste sisestuste valmistamiseks.<\/p>\n
