Cov yam ntxwv ntawm Silicon Nitride Powder

Silicon nitride (Si3N4) yog cov khoom sib xyaw ua ke ntawm silicon thiab nitrogen, nrog rau ob hom siv lead ua: thiab . -Si3N4 nthuav tawm granular crystallization, thaum -Si3N4 cov ntaub ntawv zoo li koob, ob qho tib si koom nrog hexagonal crystal system.

Nta ntawm Silicon Nitride Powder

Nitride silicon hmoov muaj cov yam ntxwv tseem ceeb hauv qab no:

Kub-kub kuj: Nitride silicon ceramic tuaj yeem tswj tau qhov kev ruaj ntseg ntawm nws cov qauv thiab cov khoom nyob rau hauv qhov kub thiab txias ib puag ncig, ua kom pom qhov kub thiab txias tsis kam.

Siab zog thiab hardness: Nitride silicon muaj lub zog txhua yam thiab hardness ze rau ntawm corundum, nrog rau nws tus kheej lubricating thiab hnav-resistant zog. Nws chav sov flexural zog tuaj yeem ncav cuag 980 MPa thiab tuav lub zog no kom txog thaum 1200 degree yam tsis poob.

Thermal stability: Nitride silicon muaj thermal stability, tsawg coefficient ntawm thermal expansion, siab thermal conductivity, thiab zoo thermal shock kuj. Nws yuav tsis tawg nyob rau hauv thermal shocks los ntawm chav tsev kub mus rau 1000 degree.

Tshuaj Stability: Nitride silicon muaj cov tshuaj lom neeg ruaj khov thiab tiv taus corrosion. Nws tsis hnov mob nrog lwm cov inorganic acids tshwj tsis yog hydrofluoric acid thiab tuaj yeem tiv thaiv corrosion ntawm sodium hydroxide (NaOH) cov kev daws teeb meem nrog cov ntsiab lus qis dua 30%. Nws kuj yog resistant rau erosion ntawm ntau cov organic tshuaj. Nitride silicon tsis ntub molten non-ferrous hlau (tshwj xeeb yog kua txhuas) thiab tuaj yeem tiv taus hluav taws xob hnyav. Hauv qhov chaw qhuav ntawm 800 degree, nws tsis hnov mob nrog oxygen. Tshaj li 800 degree, ib txheej oxidation silicon pib tsim rau saum npoo, uas maj mam stabilizes thaum kub nce. Nyob ib ncig ntawm 1000 degree, ib txheej tuab oxidation silicon tuaj yeem tsim nrog oxygen, tswj kev ruaj ntseg txog li 1400 degree.

Pob tshab microwave kev ua tau zoo thiab dielectric zog: Silicon nitride ceramics muaj cov pob tshab microwave ua tau zoo thiab cov khoom siv hluav taws xob, nrog rau lub zog kub kub, ua rau lawv tsim nyog siv los ua radar kav hlau txais xov domes rau cov cuaj luaj thiab dav hlau.

Tsawg ceev thiab nws tus kheej-Lubrication: Silicon Nitride pob khoom muaj ntau yam ntawm cov khoom siv ceev, kev tiv thaiv cov rwb thaiv tsev tsis kam, cov rwb thaiv tsev, rwb thaiv tsev, thiab tus kheej lubrication. Cov txiaj ntsig zoo no tso cai rau silicon nitride ceramic bearing npas nrog cov yam ntxwv zoo dua, ua rau lawv tshwj xeeb tshaj yog siv los ua cov ntsiab lus dov hauv hybrid ceramic pob bearings.
