Qhov muaj peev xwm tshaj plaws 7 Cov Khoom Siv Loj Oxide Ceramic! Yu Shun Sand Zeb Los Tsim Cov Khoom Siv Sib Tsoo Sib Tsoo

Oxide ceramics yog cov khoom siv tsim los ntawm oxides, feem ntau suav nrog alumina, zirconia, magnesium oxide, mullite, thiab lwm yam, uas yog sintered ntawm qhov kub thiab txias. Oxide ceramics raws li cov ntaub ntawv muaj zog, siab zog, tsis tshua muaj ntom, kub thiab corrosion kuj thiab lwm yam zoo heev, feem ntau yog siv nyob rau hauv zus tau tej cov ntaub ntawv refractory, tshav kub rwb thaiv tsev cov ntaub ntawv, melting hlau los yog alloy crucible thiab lwm yam ntim, dav siv nyob rau hauv cov khoom ntawm refractory. cav turbine hniav, kub ceev fasteners, aerospace cov ntaub ntawv, kev kho mob thiab lwm yam teb.

Nrog rau kev txhim kho ntawm cov thev naus laus zis, kev lag luam kev sib tw ntawm Tuam Tshoj cov lag luam kuj tseem nce xyoo los ntawm xyoo, thiab qee lub tuam txhab tau mus txog qib kev thev naus laus zis thoob ntiaj teb. Los ntawm kev xav ntawm daim ntawv thov teb, kev loj hlob sai ntawm tsheb, aerospace thiab lwm daim ntawv thov kev lag luam muab qhov chaw dav dav rau kev lag luam oxide ceramic. Tam sim no, Tuam Tshoj txoj kev lag luam oxide ceramic qhia txog kev loj hlob tsis tu ncua.

Oxide ceramics raws li cov ntaub ntawv sib txawv, tuaj yeem muab faib ua alumina ceramics, zirconia ceramics, magnesium oxide ceramics, beryllium oxide ceramics, tin oxide ceramics, silica ceramics, mullite ceramics, uas feem ntau siv alumina ceramics thiab zirconia ceramics.

Alumina plooj (porcelain) muaj zog txhua yam, siab ntim resistivity, zoo hluav taws xob rwb thaiv tsev kev ua tau zoo, siab zog, hnav tsis kam, oxidation tsis kam thiab lwm yam ntxwv, yog dav siv los ua cov khoom siv thiab cov khoom siv plooj (porcelain), xws li mechanical, chemical fields siv hauv hnav thiab corrosion. cov khoom tiv thaiv; Crucible, tiv thaiv tube, khoom siv refractory; Substrates, insulators, radomes, microwave electrolytes thiab lwm yam porcelain qhov chaw rau hluav taws xob kev lag luam. Alumina ceramics yog ib qho ntawm cov ceramics siab heev tau kawm ua ntej, siv dav thiab paub tab.

Zirconia ceramics yog ib qho tshiab tsim thib ob rau alumina ceramics ib qho tseem ceeb ntawm cov khoom siv ceramic, nrog cov ntsiab lus siab melting, hardness, lub zog thiab toughness, tsis tshua muaj peev xwm kub thiab thermal conductivity, tuaj yeem tsim cov pa oxygen vacancy defect thiab lwm yam ntxwv, yog siv dav. Raws li cov txheej txheem ceramics thiab kev ua haujlwm ceramics, xws li cov cuab yeej, cov khoom siv tshuab, cov khoom siv siab heev, kub anionic conductors, oxygen sensors thiab lwm yam. Txawm li cas los xij, qhov tsis zoo tseem ceeb ntawm zirconia ceramics yog tias nws lub zog thiab lub zog yog qhov hnyav heev ntawm qhov kub thiab txias, uas txwv nws daim ntawv thov ntawm qhov kub thiab txias.

Magnesium oxide ceramics yog ib yam khoom siv nrog magnesium oxide ua lub cev tseem ceeb, uas yog siv rau hauv cov yeeb yaj kiab tuab tuab. Magnesia ceramics muaj zoo conductivity, txhua yam muaj zog thiab kub tsis kam.

Beryllium oxide ceramics yog ceramics nrog beryllium oxide ua cov khoom tseem ceeb. Nws yog tsuas yog siv raws li loj-scale integrated circuit board, high-power gas laser raj, tshav kub dab dej plhaub ntawm transistor, microwave tso zis qhov rais thiab neutron moderator.

Lub thermal expansion coefficient yog me me, thermal conductivity yog siab, thiab thermal stability yog siab dua li ntawm alumina ceramics thiab zirconia ceramics. Tin oxide ceramics tsuas yog siv tau rau hauv cov pa oxygen hauv qab 1500 degree, muaj zog tiv thaiv kev yaig ntawm iav kua, tiv thaiv kev yaig ntawm cov iav txhuas, iav arsenic, iav hlau, tooj liab iav.

Nws muaj kev ruaj ntseg zoo heev, tsis tshua muaj coefficient ntawm thermal expansion, zoo heev thermal shock kuj, zoo transparency, siab ultraviolet thiab infrared transmittance, zoo hluav taws xob rwb thaiv tsev, thiab kub.

Mullite ceramics raw khoom purity yog tsawg, impurity cov ntsiab lus yog siab, yog li muaj ib tug ntau npaum li cas ntawm iav theem nyob rau hauv cov khoom, ua rau nws cov neeg kho tshuab thiab thermal zog tsis zoo, yog li ntawd mullite ceramics ntawm qhov kub thiab txias kev ua tau zoo heev tsis tuaj yeem ua si tag nrho. . Nyob rau hauv kev lag luam, zoo tib yam mullite ceramics tsuas yog siv los ua cov khoom siv refractory nyob rau hauv lub sijhawm uas qhov kub thiab txias qhov kub thiab txias yuav tsum tsis txhob siab.
