Alumina Ceramic

Alumina ceramic yog cov khoom siv ceramic raws li txhuas oxide (Al₂O₃) thiab muaj tib lub sintered siv lead ua li sapphire thiab ruby. Cov khoom siv ceramic no muaj qhov zoo heev conductivity, txhua yam muaj zog, kub tsis kam, siab resistivity, hnav tsis kam, tshuaj tsis kam, siab ceev thiab zoo rwb thaiv tsev zog. Alumina ceramics kuj tau siv dav hauv kev lag luam optoelectronic vim lawv lub teeb xa hluav taws xob siab, qis thermal expansion coefficient thiab lwm yam khoom.

1. Lub cev muaj zog: nws muaj cov yam ntxwv ntawm cov hardness siab, siab melting point thiab siab thermal expansion coefficient. Nws hardness yog thib ob tsuas yog pob zeb diamond thiab sapphire, thiab yog ib qho nyuaj tshaj plaws ntawm txhua yam khoom siv ceramic. Nws cov ntsiab lus melting yog kwv yees li 2072 degree, uas txhais tau hais tias nws tuaj yeem tswj kev ruaj ntseg hauv qhov kub thiab txias. Nyob rau tib lub sijhawm, thermal expansion coefficient ntawm nws yog tsawg thiab zoo ib yam li cov hlau, yog li nws tsis yooj yim rau deform thaum kub kub.

2. Chemical stability: nws muaj tshuaj zoo stability ntawm chav tsev kub, siab stability rau acids thiab alkali, thiab tsis yooj yim corroded. Txawm li cas los xij, yog tias nws raug dej vapor lossis huab cua hnyav ntawm qhov kub siab ntev ntev, cov tshuaj hloov pauv yuav tshwm sim uas txo nws txoj kev tiv thaiv corrosion.

3. Rwb thaiv tsev khoom: nws yog ib qho zoo heev insulating khoom nrog zoo heev hluav taws xob rwb thaiv tsev zog. Nws tuaj yeem nyob ruaj khov hauv qhov kub thiab txias thiab tsis yooj yim rau kev siv hluav taws xob. Yog li ntawd, nws feem ntau yog siv los ua insulating substrates rau cov khoom siv hluav taws xob, lub tes tsho hluav taws xob, thiab lwm yam.

4. Thermal conductivity: Txawm hais tias nws yog cov khoom siv insulating, nws cov thermal conductivity yog qhov siab. Qhov no yog vim hais tias nws yog crystalline heev thiab ntom, thiab txoj kev tshav kub conduction yog ncaj qha.

5. Biocompatibility: nws kuj tau siv dav hauv cov tshuaj thiab biotechnology. Lawv muaj biocompatibility zoo heev thiab yuav tsis ua rau khaus lossis tshuaj lom rau tib neeg cov ntaub so ntswg.

6. Hnav tsis kam: nws muaj kev hnav zoo heev, uas yog ntau dua li cov hlau zoo tib yam. Nws tuaj yeem tiv taus qhov yaig ntawm cov kua dej nrawm thiab cov khoom siv tawv tawv, thiab muaj kev hnav zoo heev thiab kev yaig tsis kam.

1. Mechanical field: nws tau siv dav hauv kev tsim cov khoom lag luam xws li cov cuab yeej txiav, pob li qub, sib tsoo lub log, cov ntsia hlau ceramic, thiab cov bearings vim lawv cov hardness siab, zoo heev los tiv thaiv hnav, thiab zoo bending zog. Cov khoom siv ceramic no tuaj yeem tswj hwm kev ua haujlwm zoo nyob rau hauv kev ua haujlwm siab ceev lossis qhov chaw ua haujlwm siab, txhim kho tag nrho kev ruaj ntseg thiab ua haujlwm ntev ntawm cov tshuab tshuab.

2. Cov hluav taws xob hluav taws xob: nws muaj cov hluav taws xob zoo heev thiab tuaj yeem tiv taus cov hluav taws xob siab heev, yog li nws tau siv dav hauv hluav taws xob hluav taws xob. Piv txwv li, nws feem ntau yog siv los ua ib qho insulator rau cov tshuab loj, xws li ceramic puag phaj, substrates, ceramics, thiab pob tshab ceramics. Tsis tas li ntawd, nws kuj tseem siv los tsim cov khoom siv hluav taws xob, cov khoom sib nqus, thiab lwm yam.

3. Kev kho mob thaj chaw: nws tau siv dav hauv kev tsim cov khoom kho mob xws li cov pob txha pob txha, cov pob qij txha, thiab cov hniav cuav vim lawv cov biocompatibility zoo thiab hnav tsis kam. Cov khoom no tuaj yeem nyob ruaj khov hauv tib neeg lub cev rau lub sijhawm ntev thiab txhim kho lub neej zoo ntawm cov neeg mob.

4. Kev lag luam tshuaj lom neeg: nws muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem ua haujlwm zoo nyob rau hauv feem ntau cov tshuaj phem ib puag ncig. Yog li ntawd, lawv feem ntau siv los tsim cov khoom siv tshuaj lom neeg thiab cov khoom tiv thaiv corrosion.

5. Lwm qhov chaw ua haujlwm siab: Ntxiv rau cov teb saum toj no, nws kuj tau siv dav hauv aerospace, high-temperature industrial furnaces, composite reinforcement and other fields. Nws zoo heev kub tsis kam thiab ruaj khov lub cev thiab tshuaj lom neeg ua rau nws yog ib qho tseem ceeb ntawm cov khoom no.
