Cov Yam Tseem Ceeb Uas Cuam Tshuam Rau Kev Ruaj Ntseg Ntawm Cov Khoom Uas Tiv Thaiv Tau Hnav

Alumina ceramics yog ib hom khoom siv ceramic nrog alumina ua lub cev tseem ceeb. Alumina ceramics muaj kev coj ua zoo dua, khoom siv kho tshuab, hnav tsis kam thiab kub tsis kam, tseem hu ua ceramics tshwj xeeb. Al2O3 ceramic khoom siv yog cov qauv hexagonal ntom ntom uas muaj cov pa oxygen ions, thiab cov txhuas ions puv rau hauv ob feem peb ntawm qhov sib txawv octahedral, uas zoo ib yam li cov qauv corundum ntuj ruaj khov α-Al2O3, yog li cov ceramic muaj qhov chaw yaj siab, tawv siab, thiab hnav tsis kam zoo heev. Alumina ceramic hardness ≥HRA85, qhov nyuaj yog qhov thib ob tsuas yog pob zeb diamond, nws qhov hnav tsis kam zoo heev.

Feem ntau hais lus, alumina ceramic txhuas yog muab faib ua hom zoo thiab hom purity siab. Hom zoo raws li Al2O3 cov ntsiab lus yog muab faib ua 92% alumina ceramic, 95% alumina ceramic, 96% alumina ceramic. Hom purity siab yog 99% alumina ceramic thiab siab dua ceramic, nws qhov kub sintering siab txog 1650-1990 ℃. 99.7% -99.9% purity siab alumina ceramics tuaj yeem siv rau hauv kev lag luam hluav taws xob ua lub rooj tsavxwm sib xyaw thiab cov ntaub ntawv rwb thaiv tsev siab, kev lag luam semiconductor hauv kev sib tsoo silicon wafers, thiab lwm yam, yog sapphire thiab semiconductor silicon wafer tshuaj lom neeg kho tshuab polishing tseem ceeb txhawb nqa cov khoom siv thiab cov khoom siv.

Qhov siab dua cov alumina cov ntsiab lus ntawm cov khoom siv ceramic uas tiv taus hnav, qhov ruaj khov dua qhov kev ua tau zoo, uas yog, qhov siab dua cov ntsiab lus ntawm txhuas, qhov zoo dua qhov kev ua tau zoo tiv taus hnav. Alumina ceramics ua cov khoom siv ceramic siab heev, nrog rau kev txhim kho sai ntawm cov khoom siv tshiab uas tiv taus hnav, yuav siv ntau dua thiab ntau dua hauv zej zog niaj hnub no.

Chemshun Ceramics muab ntau yam alumina ceramics uas muaj purity siab, xws li: 92% Al2O3 & 95% Al2O3 tus qauv hnav tsis kam alumina ceramic liner, ceramic lining pieces thiab lev, hexagon/square ceramic tile, ceramic pipe/tube/elbow, ceramic cylinder, ceramic block/cube, ceramic brick, 99.7% alumina baseboard thiab alumina wafer polishing plate, 99% alumina bulletproof ceramic, thiab lwm yam.
