Taw qhia rau aluminium nitride

Aluminium nitride (AlN) yog dawb los yog grey nonmetallic compound nrog ib tug hnyav molecular ntawm 40.98, ib tug melting point ntawm 2200 ℃, boiling point ntawm 2510 ℃, thiab ib tug ceev ntawm 3.26g / cm³.Aluminium nitride yog cov khoom siv ceramic tshiab nrog cov thermal conductivity, siab kub tsis kam, siab corrosion kuj, siab rwb thaiv tsev thiab zoo heev creep kuj, uas yog dav siv nyob rau hauv electronics, hluav taws xob fais fab, aerospace, precision instruments thiab lwm yam teb.

Cov khoom ntawm aluminium nitride

1.Thermal khoom:aluminium nitride muaj thermal conductivity, thib ob tsuas yog pob zeb diamond, thiab tuaj yeem siv tau ntev ntawm qhov kub thiab txias.

2. Mechanical zog:aluminium nitride muaj siab hardness thiab zoo hnav tsis kam.

3. Cov khoom siv hluav taws xob: aluminium nitride muaj cov rwb thaiv tsev zoo heev.

4. Optical zog:Aluminium nitride muaj cov khoom siv kho qhov muag zoo heev, thiab nws lub teeb kis tau zoo yog 200-2000nm, nrog kev xa tawm ntau dua 95%.

Txoj kev npaj ntawm txhuas nitride

Txoj kev npaj aluminium nitride feem ntau yog raws li hauv qab no:

1. Carbothermal txo txoj kev:calcium carbonate thiab alumina yog tov nrog carbon hmoov, rhuab mus rau 1500-1600 ℃ nyob rau hauv lub moj tej tawg cub tawg, kom carbon reacts nrog oxygen los tsim carbon dioxide, cov seem carbon reacts nrog calcium carbonate los tsim calcium thiab carbon dioxide, thiab thaum kawg tau txhuas. nitride.

2. Direct nitriding txoj kev:Sib tov alumina lossis txhuas ntsev nrog ammonia, ntxiv qhov tsim nyog ntawm ammonium chloride los kho tus nqi pH, tau txais ib qho nyuaj ntawm aluminium ion thiab ammonia ion, thiab tom qab ntawd kub kub ntawm qhov kub txog 1000-1200 ℃, kom ammonia decomposition rau ammonia roj. , thiab thaum kawg tau txais aluminium nitride.

3. Sputtering txoj kev:nrog lub zog siab ion beam sputtering aluminium tetrachloride thiab nitrogen, aluminium tetrachloride reacts nrog nitrogen los tsim aluminium nitride ntawm qhov kub thiab txias, thaum sau cov hmoov txhuas nitride generated.

Kev siv ntawm aluminium nitride

1. Electronic field:Aluminium nitride, raws li cov khoom siv thermal conductivity, yog dav siv hauv ntim cov khoom siv hluav taws xob, xws li semiconductor chips, transistors, thiab lwm yam.

2. Lub zog teb:Lub siab kub tsis kam thiab corrosion kuj ntawm aluminium nitride ua rau nws siv dav hauv cov tshuab fais fab, xws li transformers, capacitors thiab lwm yam.

3. Aerospace teb:aluminium nitride lub zog siab, siab hardness thiab zoo heev creep kuj ua rau nws dav siv nyob rau hauv aerospace teb, xws li aircraft cav, satellites thiab hais txog.

4. Precision ntsuas teb:Lub teeb pom kev zoo thiab cov khoom siv kho qhov muag zoo heev ntawm aluminium nitride ua rau nws siv dav hauv cov cuab yeej precision, xws li optical lo ntsiab muag, prisms, thiab lwm yam.

Kev loj hlob zeem muag ntawm aluminium nitride

Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, aluminium nitride ua ib yam tshiab ntawm cov khoom siv ceramic, nws daim ntawv thov teb txuas ntxiv nthuav dav, kev lag luam xav tau kuj nce ntxiv.Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv ntawm txhuas nitride txheej txheem kev npaj thiab txo tus nqi, aluminium nitride yuav siv rau hauv ntau qhov chaw.
