Cov yam ntxwv ua tau zoo, qhov zoo thiab qhov tsis zoo ntawm Alumina Ceramics

Cov yam ntxwv tseem ceeb ntawm alumina ceramics yog:
1. Vim nws cov kub tsis kam, corrosion kuj, thiab siab zog, nws yog zoo siv nyob rau hauv cov ntaub ntawv ntawm refractory, ceramics, thiab ironmaking blast furnaces; Spark plugs, high-temperature thiab anti-oxidation txheej.
2. Vim nws cov hardness siab, zoo hnav tsis kam, thiab siab compressive zog, nws kuj yog dav siv nyob rau hauv tshuaj systems.
3. Aluminium oxide belongs rau hom ionic thiab muaj cov qauv ruaj khov. Yog li ntawd, nws kuj tau siv dav hauv kev lag luam hluav taws xob.
4. Cov khoom siv aluminium oxide ceramic muaj cov huab cua zoo nruj thiab nruj impermeable txawm nyob rau hauv qhov kub thiab txias, yog li lawv tau siv dav hauv lub tshuab nqus tsev.
5. Cov hnav tsis kam ntawm alumina ceramics yog qhov zoo, sib npaug rau 266 npaug ntawm manganese hlau thiab 171.5 npaug ntawm cov chromium cam khwb cia hlau siab.
6. Aluminium oxide ceramic rwb thaiv tsev cov ntaub ntawv kuj tau dav siv nyob rau hauv cov phab ntsa thiab ru tsev ntawm ntau yam high-temperature resistant furnaces, uas yog ob qho tib si tshav kub-resistant thiab insulated.
7. Aluminium oxide ceramics yog lub teeb yuag, thiab qhov ntom ntawm cov ntaub ntawv ceramic feem ntau tsis siab. Aluminium oxide ceramics kuj zoo ib yam, nrog qhov ceev ntawm tsuas yog 3.5g / cubic centimeter, uas tsuas yog 50% ntawm hlau. Yog li ntawd, yog tias qee cov khoom siv hlau tau hloov nrog aluminium oxide, lawv qhov hnyav yuav raug txo kom tsawg (ntawm chav kawm, vim lub siab brittleness ntawm txhuas oxide, tsis yog txhua qhov chaw tsim nyog).
Qhov tsis zoo ntawm alumina ceramics: Txawm hais tias alumina ceramics muaj ntau qhov zoo, lawv cov kev txwv kuj tseem pom tseeb. Vim nws qhov siab hardness thiab brittleness, qhov nyuaj ntawm kev siv tshuab ua haujlwm yog qhov siab, uas tseem yog qhov laj thawj tseem ceeb rau tus nqi siab ntawm precision machined qhov chaw ntawm alumina ceramics.
