Lwm yam kev siv ntawm silicon nitride

Silicon Nitride cov khoom siv Ceramic muaj cov khoom zoo heev xws li siab thermal stability, oxidation tsis kam thiab siab qhov tseeb ntawm cov khoom. Vim tias silicon nitride yog kev sib xyaw ua ke nrog kev sib txuas lus zoo thiab tuaj yeem tsim cov yeeb yaj kiab oxide tiv thaiv cov yeeb yaj kiab hauv huab cua, nws tseem muaj cov tshuaj ruaj khov. Nws yuav tsis oxidize hauv qab no 1200 degree, thiab cov yeeb yaj kiab tiv thaiv tau tsim nyob rau 1200 ~ 1600 degrees tuaj yeem tiv thaiv cov oxidation no ntxiv. Nws yuav tsis nkag mus rau hauv cov hlau nkag los yog cov hmoov txhuas xws li txhuas, tab sis tuaj yeem ua rau muaj kua ntses xws li magnesium, Nickel- chrome hlau thiab stainless hlau.

Cov ntaub ntawv Nitride tuaj yeem siv tau los ua cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ua rau cov cuab yeej siv tshuaj ntsuab, thiab txiav cov cuab yeej hauv cov cuab yeej siv tshuab.

Txij li thaum Silicon Nitride tuaj yeem tsim cov nyiaj sib txuam nrog silicon, alumina, thorium nitride, thiab lwm yam, nws tuaj yeem siv los ua cov khoom siv thiab lwm yam.

Tsis tas li ntawd, Silicon Nitride tuaj yeem siv rau hauv cov nruab hnub ci. Tom qab Silicon Nitride Zaj Duab Xis yog tso los ntawm cov yeeb yaj kiab tso rau ntawm Silicon Nitride zaj duab xis thiab mus rau cov kev sib tw ntawm Silicon thiab rau cov haujlwm silicon Qhov sib piv ntawm nitrogen atoms hauv silicon nitride ntawm no tsis nruj 4: 3, tab sis hloov nyob rau hauv ib qho kev nyob ntawm ntau yam kev mob. Lub zog ntawm zaj yeeb yaj kiab ntawm zaj duab xis sib raug rau cov sib txawv atomic ratios sib txawv. Nws yog siv rau ultra-siab gas turbines, aircraft engins, hluav taws xob tshuab hluav taws xob, thiab lwm yam.
