Ubwino wa alumina ceramics

Alumina ceramics ndi mtundu wa zinthu za ceramic ndi Al2O3 monga zopangira zazikulu ndi corundum (a-Al2O3) monga gawo lalikulu la crystalline. Kutentha kwa sintering kwa alumina ceramics nthawi zambiri kumakhala kokwera chifukwa cha kusungunuka kwa alumina kufika pa 2050 C, zomwe zimapangitsa kupanga zoumba za alumina kuyenera kugwiritsa ntchito chotenthetsera kutentha kwambiri kapena zida zapamwamba komanso zotsutsira zapamwamba ngati ng'anjo ndi ng'anjo. , zomwe zimalepheretsa kupanga kwake komanso kugwiritsa ntchito mokulirapo. Ndiye ubwino wake ndi wotani?

Zoumba za aluminiyamu zili ndi zabwino zambiri, monga mphamvu zamakina, kuuma kwakukulu, kutayika kwa dielectric otsika pama frequency apamwamba, komanso chifukwa cha gwero lake lonse la zopangira, mtengo wotsika mtengo komanso ukadaulo wokhwima wokonzekera, umagwiritsidwa ntchito kwambiri pazinthu zamagetsi, zida zamagetsi, makina, nsalu ndi zakuthambo. Inakhazikitsanso malo ake apamwamba m'munda wa zipangizo za ceramic. Akuti zoumba za alumina ndizomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi.
