Muaj nuj nqi ntawm Silicon Nitride Powder

Nitride silicon hmoov, ua ib qho tseem ceeb ntawm cov khoom siv ceramic, muaj ntau yam zoo ntawm lub cev thiab tshuaj lom neeg, ua rau nws siv dav hauv ntau yam. Cov hauv qab no yog lub luag haujlwm tseem ceeb thiab kev siv thaj chaw ntawm nitride silicon hmoov:

1. Kub kub lub zog thiab hnav tsis kam

Silicon nitride hmoov muaj lub zog siab heev ntawm qhov kub thiab txias, tswj cov khoom siv kho tshuab ruaj khov ntawm qhov kub txog li 1200 degree. Nws hardness yog ze rau ntawm corundum, thiab nws muaj zoo hnav tsis kam. Qhov no ua rau silicon nitride hmoov zoo nyob rau hauv high-temperature thiab high-pressure ib puag ncig, haum rau manufacturing Cheebtsam uas yuav tsum tau tiv taus huab cua txias, xws li high-temperature bearings thiab gas turbine hniav.

2. Antioxidant thiab anti-corrosion zog

Nitride silicon hmoov tuaj yeem tiv taus qhov corrosion ntawm yuav luag tag nrho cov inorganic acids (tshwj tsis yog HF) thiab sodium hydroxide (NaOH) cov kev daws teeb meem nrog cov concentration hauv qab 30%. Nws kuj yog resistant rau ntau cov organic tshuaj. Qhov no ua rau nitride silicon hmoov siv dav hauv kev lag luam tshuaj rau kev tsim cov pob li qub, lub cev twj tso kua mis, lub nplhaib sib khi, cov ntxaij lim dej, thiab lwm yam khoom siv uas yuav tsum muaj kev tiv thaiv corrosion.

3. Nws tus kheej lubrication thiab tsis tshua muaj kev sib txhuam coefficient

Nitride silicon hmoov muaj nws tus kheej-lubricating zog nrog ib tug tsawg coefficient ntawm zawv zawg kev sib txhuam, ua rau nws yog ib tug zoo xaiv rau kev tsim high-temperature bearings thiab lwm yam mechanical Cheebtsam uas yuav tsum tau ib tug tsawg coefficient ntawm kev sib txhuam. Piv txwv li, nitride silicon ceramic bearings tuaj yeem ua haujlwm ntawm qhov kub txog li 1200 degree, uas yog tsib zaug siab dua qhov kev ua haujlwm kub ntawm cov bearings zoo tib yam, thaum lawv cov kev khiav hauj lwm ceev yog kaum npaug sai dua li cov bearings li niaj zaus.

4. Zoo thermal stability thiab qis coefficient ntawm thermal expansion

Nitride silicon hmoov muaj thermal stability, tsis tshua muaj coefficient ntawm thermal expansion, thiab zoo heev tshav kub conductivity, uas ua rau nws resistant rau thermal shock. Qhov no tso cai rau nitride silicon hmoov ua tau zoo hauv kev tsim cov khoom siv thermal xws li crucibles, muffle furnace chambers, thiab burners.

5. Hluav taws xob rwb thaiv tsev thiab microwave pob tshab

Nitride silicon hmoov muaj cov rwb thaiv tsev zoo heev thiab microwave permeability, uas ua rau nws siv rau hauv kev tsim khoom ntawm semiconductor, aviation, atomic zog thiab lwm yam lag luam, xws li hloov Circuit Court substrate, nyias zaj duab xis capacitor, radar kav hlau txais xov npog thiab lwm yam khoom siv hluav taws xob rwb thaiv tsev thiab microwave. permeability.

6. Biocompatibility

Nitride silicon hmoov kuj muaj biocompatibility zoo thiab tuaj yeem siv rau hauv kev kho mob kev lag luam los tsim cov pob qij txha thiab lwm yam kev cog qoob loo.

Txhawm rau ua kom tiav, silicon nitride hmoov, nrog nws cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, nthuav tawm cov haujlwm zoo heev ntawm lub zog kub, hnav tsis kam, oxidation thiab corrosion kuj, nws tus kheej lubrication, thermal stability, hluav taws xob rwb thaiv tsev, thiab biocompatibility, ua rau nws tus kheej lubrication. dav siv nyob rau hauv ntau yam xws li machinery, chemistry, electronics, aerospace, thiab tshuaj.
