Dab tsi yog qhov txawv ntawm alumina ceramics thiab zoo tib yam ceramics

1, alumina ceramic hardness

Los ntawm Tuam Tshoj Academy of Sciences Shanghai Lub Tsev Haujlwm ntawm Ceramics, nws qhov hardness Rockwell yog HRA80-90. Hardness yog thib ob tsuas yog pob zeb diamond, ntau dua li hnav cov hlau tsis muaj zog thiab stainless hlau hnav tsis kam.

2, alumina ceramic hnav kuj zoo heev

Ntsuas los ntawm lub koom haum ntawm hmoov Metallurgy, Central South University, nws hnav tsis kam yog sib npaug rau manganese hlau 266 zaug, siab chromium cam khwb cia hlau 171.5 zaug. Raws li peb ntau tshaj kaum xyoo ntawm kev soj ntsuam cov neeg siv khoom, nyob rau hauv tib txoj haujlwm ua haujlwm, tsawg kawg tuaj yeem ncua sijhawm kev pabcuam ntawm cov khoom siv ntau tshaj kaum zaug.

Qhov sib txawv tseem ceeb ntawm alumina ceramics thiab cov ceramics zoo tib yam yog cov khoom siv raw ntawm ceramics raug xaiv nruj me ntsis, uas yog, kom tau txais ntau npaum li qhov ua tau kom tau raws li qhov yuav tsum tau muaj ntawm lub siab purity ntawm thawj tsev neeg, thiab qhov loj me ntawm cov khoom raws li zoo li ua tau. Qhov thib ob yog kev tswj xyuas meej ntawm nws cov tshuaj muaj pes tsawg leeg.

3. Alumina ceramics yog lub teeb hauv qhov hnyav

Nws qhov ceev yog 3.5g / cm3, tsuas yog ib nrab ntawm cov hlau, uas tuaj yeem txo cov khoom siv ntau.
