Lub tswvyim txawv
Alumina ceramic yog ib yam khoom siv ceramic nrog alumina (AI203) ua lub cev tseem ceeb.
Pob tshab ceramics yog tau los ntawm kev siv siab purity ultra-fine ceramic raw cov ntaub ntawv thiab tshem tawm cov pores los ntawm kev siv technology.
Kev sib xyaw thiab kev faib tawm txawv
Alumina ceramics tau muab faib ua hom purity siab thiab zoo tib yam hom ob.
High-purity alumina ceramics yog cov khoom siv ceramic nrog AI203 cov ntsiab lus siab dua 99.9% Vim nws qhov kub thiab txias li 1650-1990.℃thiab kis tau tus mob wavelength ntawm 1 ~ 6um, nws yog feem ntau ua rau molten iav coj ib tiam ntawm platinum crucible;Siv nws lub teeb kis tau tus mob thiab alkali hlau corrosion kuj raws li sodium teeb raj;Nws tuaj yeem siv los ua kev sib koom ua ke ntawm pawg thawj coj saib thiab cov khoom siv hluav taws xob ntau zaus hauv kev lag luam hluav taws xob.
Ordinary alumina ceramics tau muab faib ua 99 plooj (porcelain), 95 plooj (porcelain), 90 plooj (porcelain), 85 plooj (porcelain) thiab lwm yam ntau yam raws li cov ntsiab lus ntawm A1203, thiab qee zaum cov ntsiab lus A1203 kuj tau muab faib ua alumina ceramics series.99 alumina ceramic khoom siv los ua kom kub kub crucible, refractory furnace yeeb nkab thiab tshwj xeeb hnav-resistant cov ntaub ntawv, xws li ceramic bearings, ceramic seals thiab dej li qub;95 alumina porcelain feem ntau yog siv los ua corrosion kuj thiab hnav tsis kam;Lub 85 plooj (porcelain) feem ntau yog tov nrog talc los txhim kho cov khoom siv hluav taws xob thiab cov khoom siv dag zog, thiab tuaj yeem raug kaw nrog molybdenum, niobium, tantalum thiab lwm yam hlau, thiab qee qhov siv los ua cov khoom siv hluav taws xob.
Pob tshab ceramics tuaj yeem muab faib ua aluminium oxide pob tshab ceramics, yttrium oxide pob tshab ceramics, magnesium oxide pob tshab ceramics, yttrium aluminium garnet pob tshab ceramics, aluminium magnesium acid pob tshab ceramics, pob tshab ferroelectric ceramics, aluminium nitride pob tshab ceramics, aluminium nitride pob tshab ceramics, magnesium aluminium spinel pob tshab ceramics thiab lwm yam.
Kev ua tau zoo sib txawv
Alumina ceramic khoom:
1. High hardness txiav txim los ntawm Shanghai lub koom haum ntawm Silicate ntawm Suav Academy ntawm Sciences, nws Rockwell hardness yog HRA80-90, lub hardness yog thib ob rau pob zeb diamond, deb tshaj qhov hnav tsis kam ntawm hnav-resistant steel thiab stainless hlau.
2. Kev hnav zoo heev ntsuas los ntawm Powder Metallurgy Institute ntawm Central South University, nws hnav tsis kam yog sib npaug rau 266 npaug ntawm manganese hlau thiab 171.5 npaug ntawm cov chromium cam khwb cia hlau.Raws li peb cov neeg siv khoom taug qab kev soj ntsuam rau ntau tshaj kaum xyoo, nyob rau hauv tib lub sijhawm ua haujlwm, kev pabcuam lub neej ntawm cov khoom siv tuaj yeem txuas ntxiv yam tsawg kawg kaum zaug.
3. Lub teeb yuag Nws qhov ceev yog 3.5g / cm3, uas tsuas yog ib nrab ntawm cov hlau, uas tuaj yeem txo cov khoom thauj khoom zoo heev.
Pob tshab ceramic khoom:
Pob tshab ceramics raws li ib ceg ntawm cov ceramics siab heev, ntxiv rau kev sib txuas ntawm ceramics kub tsis kam, corrosion kuj, siab zog, siab hardness, tshuaj stability, tsis tshua muaj expansion coefficient nyob rau hauv tas li ntawd, lub cim teeb kis tau tus mob ua rau nws nce ntau daim ntawv thov.
Daim ntawv thov sib txawv
Alumina ceramics tau dav siv hauv tshuab, kho qhov muag fiber, txiav cov cuab yeej, kho mob, zaub mov, tshuaj, aerospace thiab lwm yam lag luam.
Pob tshab ceramics feem ntau yog siv rau hauv cov khoom siv teeb pom kev zoo, cov khoom siv laser, cov ntaub ntawv infrared qhov rais, flicker ceramics, electro-optical ceramics, cov ntaub ntawv mos mos.
