Qhov Zoo Thiab Kev Siv Cov Khoom Siv Boron Nitride

BN feem ntau yog nyob rau hauv daim ntawv hexagonal siv lead ua (zoo ib yam li graphite), uas tuaj yeem hloov mus rau hauv daim ntawv siv lead ua cubic (zoo ib yam li pob zeb diamond superhard khoom) nyob rau hauv qhov kub thiab txias siab. Nws muaj zoo thermal poob siab stability, zoo acid thiab alkali corrosion kuj, thiab yuav machined. Nws tuaj yeem ncav cuag 2800 degree thaum siv hauv qhov chaw tsis muaj zog.

1.Vim tias BN muaj thermal conductivity, hluav taws xob rwb thaiv tsev, tsis tshua muaj ceev, siab reflectivity, thiab zoo heev qhuav lubrication kev kawm.

Zoo pwm compatibility rau synthesis, extrusion thiab txhaj tshuaj molding txheej txheem tso cai rau nws yuav tsum tau formulated rau hauv ntau thermoplastics, elastomers, thermosets thiab adhesives. Lawv pab dissipate cua sov hauv cov neeg siv khoom siv hluav taws xob thiab txhim kho kev tswj xyuas thermal hauv cov roj teeb muaj peev xwm, LEDs, thiab kev siv tsheb. BN sau cov tebchaw ua haujlwm ua ke nrog kev tswj hwm thermal nrog hluav taws xob rwb thaiv tsev, thaum tseem ua kom sib dua, yooj yim cov qauv tsim uas tuaj yeem txo cov nqi tag nrho.

2. Hauv kev lag luam hluav taws xob, nws yog siv los ua lub qhov rais xa mus rau radar los ntawm kev siv nws cov thermal conductivity thiab nkag mus rau microwave hluav taws xob.

3. Lub thermal conductivity ntawm kub nias hexagonalBNyog sib npaug ntawm cov hlau tsis muaj steel, thiab tsis hloov ntau nrog qhov kub thiab txias, thiab nws cov thermal conductivity zoo dua BeO hauv qab 900 degree. HexagonalBNNws muaj cov thermal expansion coefficient tsawg thiab elastic modulus, yog li nws muaj thermal stability zoo heev thiab tuaj yeem siv nyob rau hauv qhov rov ua kom txias thiab ceev cua sov los ntawm 1500 ° C mus rau chav tsev kub.

4. BNmuaj corrosion kuj zoo rau cov kua qaub, alkali thiab iav slag, thiab tsis ntub rau feem ntau molten hlau xws li Fe, Al, Ti, Cu thiab Si, thiab lwm yam, nrog rau gallium arsenide, cryolite thiab iav yaj. Nws kuj tsis hnov ​​​​mob, yog li nws tuaj yeem siv los ua crucibles, cov hlab ntsha, cov kav dej, cov twj xa khoom thiab lwm qhov chaw rau melting non-ferrous metals, precious hlau thiab tsis tshua muaj hlau. Nws kuj tseem siv tau los ua boron ib leeg siv lead ua melting hlab ntsha, iav tsim pwm, kab rov tav nruam casting sib cais rings, thermoelectric Couple tiv thaiv raj, thiab lwm yam., kuj tuaj yeem siv los tsim cov thawv rau cov khoom siv semiconductor xws li zinc arsenide, gallium phosphide, thiab indium. phosphide, tshav kub dissipation hauv qab daim hlau rau ntau pob khoom semiconductor, thiab P-hom diffusion qhov chaw rau semiconductors thiab integrated circuits.

5. Lub boron nitride thermocouple tiv thaiv raj yog siv los hloov cov pa alumina tiv thaiv raj. Vim tias thermal conductivity ntawm boron nitride thermocouple tiv thaiv raj zoo dua, kev tswj qhov kub thiab txias tau raug txhim kho, lub zog txuag hluav taws xob ntawm qhov cub yog qhov zoo tshaj plaws, thiab cov khoom tsim nyog tus nqi tau txhim kho. , tuaj yeem nqa cov txiaj ntsig kev lag luam zoo dua rau kev lag luam.

6. Vim muaj cov boron atoms, boron nitride muaj peev xwm nqus tau cov noob. Nws yog siv rau hauv kev lag luam atomic zog ua ke nrog ntau yam yas thiab graphite, thiab tuaj yeem siv los ua cov ntaub thaiv npog rau atomic pawg.

7. BNyog ruaj khov nyob rau hauv ultra-siab siab thiab yuav siv tau los ua ib lub thawv rau siab kis cov ntaub ntawv.BNyog cov khoom siv hluav taws xob zoo tshaj plaws, uas muaj txiaj ntsig zoo rau cov khoom siv hluav taws xob kub ntawm cov dav hlau thiab cov khoom siv dav hlau.
