Hexagonal boron nitrideThiab nws cov khoom siv tau npaj los ntawm cov xovxwm kub sintering yog zoo li kev ua haujlwm siab, nce siab heev { Nws cov khoom tseem ceeb: 1. High cua sov tiv taus: Oxidation pib ntawm 9000℃hauv lub tshuab pa oxidation, thiab 2800℃tsis soften hauv cov roj inert; Nws lub zog yog 1800℃ob zaug ntawm chav tsev kub, 2. Siab thermal conductivity: Cov khoom kub xovxwm yog 33w
Hexagonal Boron Nitride thiab nws cov khoom siv hluav taws xob tau npaj tau zoo, ua haujlwm siab ua haujlwm siab, nce siab heev {1} tsis - pa.
Nws lub ntsiab kev ua tau:
1. Muaj kub kub tiv: oxidation pib ntawm 900℃nyob rau hauv ib qho chaw oxidation, thiab tuaj yeem nyab xeeb nyob rau hauv lub tshuab nqus pa, thiab 2800℃tsis soften hauv cov roj inert; Nws lub zog yog 1800℃ob zaug ntawm chav tsev kub.
2. Siab thermal conductivity: qhov kub - · k} · k}, thiab yog ib qho khoom siv ntshiab ntawm cov ntaub ntawv ceramic saum 530 degree;
3. Tsawg Tsawg Thermal nthuav tawm coefficient: Qhov nthuav dav coefficient ntawm 2 × 10 {}}}}}
4. Zoo hluav taws xob cov khoom: Zoo siab-} cm, thiab 2000℃tuaj yeem ncav cuag 103}} cm. Nws yog qhov zoo siab -} sov rwb thaiv tsev cov khoom nyob rau hauv ceramics, nrog ib tug tawg voltage ntawm 3kv / hli. Tsawg dielectric ploj, 2 ~ 5 × 10-4 ntawm 108Hz, diteectric tas li yog 4, thiab tuaj yeem hloov kho microwave thiab infrared rays;
5. Zoo corrosion Kuj: tsis muaj kev cuam tshuam nrog cov hlau hluavtaws dav (cov khoom siv roj av, cov tshuaj fluorcium, slag), inorganic acids thiab alkalis;
6. Kev sib txhuam qis dua coefficient: μ yog 0.16, thiab tsis nce ntxiv ntawm qhov kub siab;
7. Cov neeg kho tshuab Machining: nws lub hardness yog Mohs 2, yog li nws tuaj yeem ua tiav rau hauv cov qauv thiab kev ua kom raug rau 0.01 hli.
Raws li cov khoom saum toj no, boron nitride thiab nws cov ntaub ntawv sib xyaw muaj ntau cov siv hauv kev txiav ing ...} uge ntug, metallurgy, chemical:
1. Siv cov tshuaj ruaj khov zoo ntawm Hexagonal Boron Nitride cov khoom siv roj av, cov pob zeb ua kua, cov pwm ua kom muaj zog, pwm rau cam steel, thiab lwm yam ;;
2. Siv cov cua sov thiab corrosion tsis kam ntawm hexagonal boron nitride cerams, rockecion {}} Flow Generators, thiab lwm yam;
3. Siv cov khoom siv insulating ntawm hexagonal boron nitride ceramics, thiab cov cua sov}}}}}} zaus hluav taws xob tshuab hluav taws xob.
4. Siv cov rwb thaiv tsev siab thiab siab thermal conductivity ntawm hexagonal boron nitride lub cerformers, thiab siab} {voltage insulated tshav kub dissulation Cheebtsam sov;
5. Siv cov cua sov tsis kam, corrosion tsis kam thiab rwb thaiv tsev zog ntawmhexagonal boron nitrideCeramics, High - Kev Tiv Thaiv Cov Khoom Siv Plasma, cov cuab yeej siv hluav taws xob
6. Siv cov khoom lag luam loj poob qis, microwave kev sib zog kis lub qhov rais tuaj yeem ua, thiab cov tawv domuses Tau nrog cov ntsiab lus siab B B ntsiab lus tuaj yeem siv ua semiconductors.
