99 alumina ceramics muaj qhov zoo ntawm qhov muaj qhov siab melting point, siab hardness, thiab siab mechanical zog, txawm hais tias lub zog mechanical kub yog txo kom ntau tshaj 1000 degree.
Vim qhov nce ntawm cov thermal expansion coefficient loj heev, yog li lub thermal poob siab stability yog txo, 99 alumina ceramic kom zoo dua yog ib hom hluav taws xob rwb thaiv tsev cov khoom, nrog siab resistivity.
Nws kuj muaj tshuaj lom neeg ruaj khov ntawm alumina, yog li zoo corrosion kuj, 99 alumina yog insoluble nyob rau hauv dej, tsuas yog me ntsis soluble nyob rau hauv muaj zog acid thiab alkaline aqueous tov.
Ceramic txhaj tshuaj molding thiab precision sib tsoo feem ntau yog siv los tsim ntau yam complex Cheebtsam nrog nruj nto tiav thiab flatness yuav tsum tau.
Cov khoom siv no feem ntau siv rau hauv kev tswj dej, kev kho mob, tsheb, kev sib txuas lus thiab khoom siv. Alumina yog qhov zoo tshaj plaws engineering ceramics, nws muab cov hluav taws xob rwb thaiv tsev zoo heev, siab hardness thiab hnav tsis kam tab sis kuj tsis tshua muaj zog thiab tawg toughness.
