Alumina ceramics waa nooc ka mid ah walxaha dhoobada leh Al2O3 oo ah alaabta ceeriin ee ugu weyn iyo corundum (a-Al2O3) oo ah wejiga ugu weyn ee crystalline. Heerkulka dhoobada alumina ee ceramics guud ahaan wuu sarreeyaa sababtoo ah barta dhalaalaysa ee alumina ilaa 2050 C, taas oo ka dhigaysa wax soo saarka dhoobada alumina inay u baahan yihiin kuleyliyaha heerkul sare ama qalab tayo sare leh iyo refractors heer sare ah sida alaabta foornada iyo foornada. , kaas oo ilaa xad xaddidaya wax soo saarkiisa iyo codsigiisa ballaaran. Haddaba waa maxay faa'iidooyinka ay leedahay?
ceramics Alumina leeyihiin faa'iidooyin badan, sida xoog farsamo sare, qallafsanaan sare, khasaaraha dielectric hoose at soo noqnoqoshada sare, iyo sababta oo ah isha ballaaran ee alaabta ceeriin, qiimo jaban iyo tignoolajiyada processing baaluq, waxaa si ballaaran loo isticmaalaa in beeraha ee elektarooniga ah. qalabka korontada, mishiinada, dunta iyo hawada. Waxa kale oo ay dejisay booskeeda sare ee berrinka alaabta dhoobada. Waxaa la sheegay in ceramics-ka alumina ay yihiin dhoobada oksaydhka ee loogu isticmaalka badan yahay adduunka.
