Alumina ceramics nrog plasma corrosion kuj zoo heev thiab hnav tsis kam

Alumina ceramics yog ib yam ntawm cov khoom siv ceramic, peb tuaj yeem txhim kho daim ntawv thov kev ua tau zoo thiab kev ua haujlwm ntawm alumina ceramics los ntawm kev ntxiv aluminium oxide hmoov rau hauv cov ceramics, nrog kev ua haujlwm zoo, txhua yam muaj zog thiab kub tsis kam, yog ib qho ntawm feem ntau siv. ceramics.

Qhov txiaj ntsig tseem ceeb ntawm alumina ceramics yog tias nws lub zog khoov yog qhov siab heev, thiab cov qib ntawm kev kub siab yog ntau dua li lwm cov ntaub ntawv ntawm tib hom. Nyob rau hauv cov nqe lus ntawm Mohs hardness yog invincible, tshwj xeeb kom zoo dua, ua ke nrog zoo heev hnav tsis kam, yog li nws yog feem ntau siv los ua cov cuab yeej, ceramic bearings ... thiab lwm yam. Cov cuab yeej ceramic thiab cov khoom lag luam yog cov kev xaiv tam sim no rau kev siv alumina ceramic.

2. Chemical teb

Alumina cov ntaub ntawv tseem muaj lub neej yav tom ntej hauv kev lag luam tshuaj, txawm hais tias nws yog cov khoom ntim tshuaj lom neeg lossis cov txheej txheem tiv thaiv corrosion, cov ntaub ntawv inorganic polymer siv yuav tsum yog kub tsis kam thiab zoo thermal stability. Alumina ceramics yuav tsis raug compressed nyob rau hauv siab zog thiab siab siab, tuaj yeem tiv taus qhov yaig ntawm cov kuab tshuaj organic thiab cov khoom siv tshuaj lom neeg, tuaj yeem siv ntau zaus, thiab ua tau raws li cov xwm txheej ntawm kev ua haujlwm tshuaj.

3. Electronic-electricity nam

Alumina ceramics tseem ua lub luag haujlwm tseem ceeb hauv hluav taws xob-hluav taws xob nam, thiab ntau yam ceramic substrates, ceramics, pob tshab ceramics thiab insulating li yog inseparable ntawm alumina ceramics. Hauv kev lag luam hluav taws xob loj, pob tshab ceramics yog ib qho tseem ceeb ntawm kev tshawb fawb tam sim no thiab kev siv cov cuab yeej tshiab, tsis tsuas yog muaj ntau yam ntawm lub teeb kis tau tus mob, siab thermal conductivity, tsis tshua muaj conductivity, hnav tsis kam thiab ntau yam zoo dua. .

4. Kev tu cev hauv tsev

Daim ntawv thov ntawm alumina ceramic hauv ob sab phlu cib thiab microcrystalline hnav-resistant alumina spherical pob zeb rau pob zeb tau nrov heev, thiab daim ntawv thov ntawm alumina ceramic roller, alumina ceramic lim raj thiab ntau yam alumina thiab alumina ua ke nrog lwm cov ntaub ntawv refractory tuaj yeem pom nyob txhua qhov chaw.

5. Lwm yam

Ntau yam sib xyaw thiab hloov kho alumina ceramics xws li carbon fiber reinforced alumina ceramics, zirconia reinforced alumina ceramics thiab lwm yam toughened alumina ceramics yog nce siv nyob rau hauv high-tech teb; Alumina ceramic abrasives thiab qib siab polishing pastes tau ua lub luag haujlwm tseem ceeb hauv kev lag luam tshuab thiab cov hniav nyiaj hniav kub; Tsis tas li ntawd, alumina ceramic sib tsoo nruab nrab muaj qhov ua tau zoo tshaj plaws hauv kev sib tsoo thiab ua cov khoom siv raw hauv cov txheej txheem thiab tshuaj lag luam.
