Densely sintered txhuas oxide ceramic oxide ceramic, feem ntau hu ua alumina (Al2o3), yog cov khoom siv ua haujlwm siab, cov khoom siv hluav taws xob, thiab hluav taws xob. Nws yog tsim los ntawm cov txheej txheem hu ua sintering, uas yuav tsum tau compacting nplua aluminium oxide hmoov rau hauv ib qho kev xav tau thiab tom qab ntawd muab lawv mus rau qhov kub thiab txias kom fuse cov khoom ua ke.

Cov yam ntxwv ntawm Densely Sintered Aluminium Oxide Ceramic

Siab Hardness

Alumina paub txog nws qhov tshwj xeeb hardness, ua rau nws haum rau cov ntawv thov uas hnav tsis kam yog qhov tseem ceeb. Nws yog feem ntau siv nyob rau hauv ib puag ncig abrasive.

High Thermal conductivity

Nws muaj cov thermal conductivity zoo, uas ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov uas xav tau kev hloov pauv hluav taws xob zoo, xws li hauv qee hom insulators thiab cov dab dej kub.

Hluav taws xob rwb thaiv tsev

Alumina yog cov khoom siv hluav taws xob zoo heev, ua rau nws muaj txiaj ntsig zoo hauv kev siv hluav taws xob thiab hluav taws xob. Nws yog feem ntau siv nyob rau hauv cov khoom xws li insulating washers, substrates, thiab high-voltage insulators.

Tshuaj tiv thaiv

Nws tiv taus ntau yam tshuaj, uas ua rau nws tsim nyog rau cov ntawv thov uas raug rau cov tshuaj corrosive yog ib qho kev txhawj xeeb.

Dimensional Stability

Alumina nthuav tawm tsis tshua muaj thermal expansion, txhais tau tias nws tuav nws cov duab thiab qhov loj ntawm ntau qhov kub thiab txias. Cov cuab yeej no yog qhov tseem ceeb hauv cov ntawv thov uas yuav tsum muaj kev zam nruj.

Biocompatibility

Qee hom alumina yog biocompatible thiab tuaj yeem siv rau hauv kev kho mob, xws li kev cog hniav thiab kev sib koom ua ke.

Pob tshab

Nyob rau hauv nws daim ntawv high-purity, alumina tuaj yeem ua pob tshab, tso cai rau kev sib kis ntawm qee qhov wavelengths ntawm lub teeb. Cov cuab yeej no yog siv rau hauv cov ntawv thov xws li qhov rais rau lub tshuab nqus tsev thiab UV-Vis spectroscopy.

Kub-kub Resistance

Alumina tuaj yeem tiv taus qhov kub thiab txias, ua rau nws tsim nyog rau kev siv hauv kev lag luam xws li aerospace, qhov twg cov khoom yuav raug kub hnyiab.

Mechanical Strength

Nws muaj lub zog zoo txhua yam, uas yog qhov tseem ceeb rau cov ntawv thov uas cov khoom yuav raug rau cov neeg kho tshuab kev nyuaj siab.

Nqi-zoo

Piv nrog rau lwm cov khoom siv ceramics siab heev, alumina nyhav rau tus nqi zoo.
