Kusiyana pakati pa alumina ceramics ndi ma ceramics owonekera

Lingaliro losiyana

Alumina ceramic ndi mtundu wa zinthu za ceramic ndi alumina (AI203) monga thupi lalikulu.

Ma ceramics owoneka bwino amapezedwa pogwiritsa ntchito zopangira zoyera kwambiri za ceramic ndikuchotsa pores pogwiritsa ntchito ukadaulo.

Mapangidwe ndi magulu ndizosiyana

Zoumba za aluminiyamu zimagawidwa kukhala mtundu wachiyero kwambiri komanso mtundu wamba wachiwiri.

Zitsulo za alumina zoyera kwambiri ndi zida za ceramic zomwe zili ndi AI203 pamwamba pa 99.9%.℃ndi kutalika kwa kutalika kwa 1 ~ 6um, nthawi zambiri amapangidwa kukhala galasi losungunuka kuti atenge mbadwo wa platinamu crucible;Gwiritsani ntchito kuwala kwake ndi kukana kwachitsulo chachitsulo ngati sodium chubu;Itha kugwiritsidwa ntchito ngati gulu lophatikizika lozungulira komanso zinthu zambiri zotchinjiriza pafupipafupi pamakampani azamagetsi.

Ma aluminiyamu wamba amagawidwa mu 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain ndi mitundu ina malinga ndi zomwe zili mu A1203, ndipo nthawi zina zomwe zili mu A1203 zimatchulidwanso ngati mndandanda wamba wa alumina ceramics.Zida za 99 alumina ceramic zimagwiritsidwa ntchito popanga crucible kutentha kwambiri, chitoliro cha ng'anjo yoyaka moto ndi zida zapadera zosavala, monga ma bere a ceramic, zisindikizo za ceramic ndi ma valve amadzi;95 alumina porcelain amagwiritsidwa ntchito makamaka ngati kukana dzimbiri komanso kukana kukana;85 porcelain nthawi zambiri amasakanizidwa ndi talc kuti apititse patsogolo mphamvu zamagetsi ndi mphamvu zamakina, ndipo amatha kusindikizidwa ndi molybdenum, niobium, tantalum ndi zitsulo zina, ndipo zina zimagwiritsidwa ntchito ngati zida zamagetsi.

Zoumbala zowonekera zitha kugawidwa mu zoumba zotayidwa oxide mandala, yttrium okusayidi mandala ziwiya zadothi, magnesium oxide mandala ziwiya zadothi, yttrium aluminium garnet mandala ziwiya zadothi, aluminium magnesium acid mandala ziwiya zadothi, mandala ferroelectric ceramics, aluminium nitride transparent ceramics, aluminium spine aluminium transparent ceramics, aluminium spine ma ceramics owonekera ndi zina zotero.

Zochita zosiyanasiyana

Alumina ceramic katundu:

1. Kuuma kwakukulu kotsimikiziridwa ndi Shanghai Institute of Silicate ya Chinese Academy of Sciences, kuuma kwake kwa Rockwell ndi HRA80-90, kuuma kwake ndi kwachiwiri kwa diamondi, kupitirira kwambiri kukana kuvala kwa chitsulo chosagwira ntchito ndi chitsulo chosapanga dzimbiri.

2. Kukaniza kovala bwino Kuyesedwa ndi Powder Metallurgy Institute of Central South University, kukana kwake kuvala kumakhala kofanana ndi nthawi za 266 zachitsulo cha manganese ndi nthawi 171.5 zachitsulo chapamwamba cha chromium.Malinga ndi kafukufuku wathu wotsata makasitomala kwa zaka zopitilira khumi, pansi pamikhalidwe yomweyi yogwirira ntchito, moyo wautumiki wa zidazo ukhoza kukulitsidwa nthawi zosachepera khumi.

3. Kulemera kwake Kuchuluka kwake ndi 3.5g / cm3, yomwe ili theka lazitsulo, zomwe zingathe kuchepetsa kwambiri katundu wa zipangizo.

Transparent ceramic katundu:

Ma ceramics owoneka ngati nthambi yazitsulo zapamwamba, kuphatikiza kutengera kukana kutentha kwa ceramic, kukana dzimbiri, kulimba kwamphamvu, kulimba kwamphamvu, kukhazikika kwamankhwala, kutsika kwachulukidwe kocheperako kuwonjezera, kufalikira kwapadera kwapadera kumapangitsa kuti ziwonjezere ntchito zambiri.

Ntchito zosiyanasiyana

Alumina ceramics amagwiritsidwa ntchito kwambiri pamakina, ulusi wa kuwala, zida zodulira, zamankhwala, chakudya, mankhwala, zakuthambo ndi mafakitale ena.

Ma Ceramics owonekera amagwiritsidwa ntchito makamaka pazowunikira zowunikira, zida za laser, zida zamawindo a infuraredi, zoumba zowuluka, zoumba zama electro-optical, zida zoteteza zipolopolo.
