Cov khoom siv ntawm silicon nitride
Silicon nitride muaj zog heev, tshwj xeeb tshaj yog kub nias silicon nitride, uas yog ib qho nyuaj tshaj plaws nyob rau hauv lub ntiaj teb no. Nws yog qhov tiv taus kub heev, thiab nws lub zog tuaj yeem khaws cia kom txog thaum kub ntawm 1200 degree tsis poob, thiab nws yuav tsis yaj mus rau hauv cov yaj tom qab cua sov, thiab nws yuav tsis decompose mus txog 1900 degree, thiab nws muaj kev tiv thaiv zoo heev. corrosion kev ua tau zoo, muaj peev xwm tiv taus yuav luag txhua yamInorganic acids thiab tsawg dua 30% caustic soda tov, kuj tuaj yeem tiv thaiv corrosion ntawm ntau cov organic acids; Nyob rau tib lub sijhawm, nws yog cov khoom siv hluav taws xob ua haujlwm siab.
Lwm yam kev siv ntawm silicon nitride
Silicon nitride ceramic cov ntaub ntawv muaj: Thermal stabilityHigh kev ua tau zoo, muaj zog oxidation tsis kam thiab siab qhov tseeb ntawm cov khoom. Txij li thaum silicon nitride yog ib qho kev cog lus siab zogCovalent compoundsand tuaj yeem tsim cov oxide tiv thaiv zaj duab xis hauv huab cua, yog li nws kuj muaj tshuaj lom neeg ruaj khov Nws tsis yog oxidized hauv qab 1200 degree, thiab cov yeeb yaj kiab tiv thaiv tsim tawm ntawm 1200 ~ 1600 degree tuaj yeem tiv thaiv oxidation ntxiv, thiab Nws tsis yog infiltrated los yog corroded los ntawm ntau molten hlau los yog alloys xws li txhuas, txhuas, tin, nyiaj, tooj dag, npib tsib xee, thiab lwm yam, tab sis tuaj yeem nkag mus los yog corroded los ntawm magnesium, Nichrome, stainless hlau thiab lwm yam molten kua.
