SUOYI Boron Nitride Powder BN hexagonal boron nitride HBN CBN RBN WBN

Boron nitride ke kristale e entsoeng ka liathomo tsa nitrogen le liathomo tsa boron. Sebopeho sa kristale se arotsoe ka hexagonal boron nitride (HBN), e pakiloeng ka mahlakore a mabeli a boron nitride (WBN) le cubic boron nitride. Sebopeho sa kristale sa hexagonal boron nitride se na le sebopeho se ts'oanang sa graphite, se bonts'ang ho hlephileng, ho tlotsoa, ​​ho monya mongobo habonolo, boima bo bobebe le litlhaku tse ling tsa phofo e tšoeu, kahoo e boetse e bitsoa "graphite e tšoeu".

Theory density 2.27g/ cm3, matla a khoheli a khethehileng: 2.43, Mo hardness ke 2.

Hexagonal boron nitriding e na le insulation e ntle ea motlakase, conductivity ea mocheso, botsitso ba lik'hemik'hale, ha ho na ntlha e hlakileng ea ho qhibiliha, ho hanyetsa mocheso ho 0.1MPA nitrogen ho 3000ºC, moeeng oa ho fokotsa ho se nke lehlakore, ho hanyetsa mocheso ho 2000ºC, naetrojene le argon ha mocheso o sebelisoa o ka fihla ho 2800ºC, sepakapakeng sa oksijene botsitso ha bo bobe, tšebeliso ea mocheso o ka tlase ho 1000ºC.

Hexagonal boron nitride e na le coefficient ea katoloso e tšoanang le ea quartz, empa mocheso oa eona oa mocheso o mena ka makhetlo a leshome ho feta oa quartz. E boetse e na le lubricity e ntle mochesong o phahameng, ke setlolo se tiileng sa mocheso o phahameng se phahameng, se na le matla a matla a ho monya neutron, botsitso ba lik'hemik'hale, 'me ha se na lik'hemik'hale hoo e ka bang litšepe tsohle tse qhibilihisitsoeng.

Hexagonal boron nitriding insoluble metsi a batang, metsi a belang hydrolysis e butle haholo 'me e hlahisa palo e nyenyane ea boric acid le ammonia,' me acid e fokolang le botlaaseng bo matla mocheso oa kamore ha e sebetse, e qhibiliha hanyenyane ka acid e chesang, e nang le sodium hydroxide e qhibilihisitsoeng, hydroxide potassium. phekolo ho bola. E na le khanyetso e kholo ea kutu ho li-acid tse fapaneng tsa inorganic, metheo, litharollo tsa letsoai le li-solvents tsa organic.

● Ha e khone ho futhumala

● Ha e khone ho mamella lik'hemik'hale

● E sa tsitsang ka lik'hemik'hale 'me e tsitsitse

● Low mogote conductivity

● Katoloso e tlase ea mocheso

● Dielectric e tlaase kamehla

● Ho se kolobise (khalase, matsoai, litšepe tse ling)

● Ho itšehla thajana

● E entsoe habonolo

Hexagonal boron nitride ke mofuta oa thepa e tsoetseng pele ea ceramic. Microstructure ea eona e fokola 'me sebopeho sa eona sa molek'hule ke kristale ea hexagonal. Hexagonal boron nitride e na le thepa e khethehileng haholo le e babatsehang ea 'mele le lik'hemik'hale. E na le conductivity e ntle haholo ea mocheso, ho kenya motlakase, ho hanyetsa ho bola ha lik'hemik'hale le khanyetso ea oxidation. E khona ho mamella ho fihla ho 1000OC moeeng, le ho fihla ho 2000OC ka khase ea inert le vacuum. Crystalline boron nitride e 'nile ea silafatsoa ka mocheso o phahameng oa 2000OC, e nang le lik'hemik'hale tse tsitsitseng le thepa ea' mele le mekhoa e metle ea mocheso (mocheso oa mocheso oa kristale e le 'ngoe e ka bang 250-300W / mk). Hajoale, k'hamphani e hlahisa phofo ea kristale ea flake e nang le boholo bo le bong ba kristale ea 500 nanometer-20 microns le nanoscale spherical boron nitride.

Hexagonal boron nitride e ratoa ke indasteri ea elektroniki ka lebaka la maemo a eona a sa tloaelehang a conductivity e phahameng ea mocheso le ts'ebetso ea ho kenya motlakase. Baetsi ba elektronike ba malapeng le ba linaheng tse ling ba entse lipatlisiso tse kholo tsa lisebelisoa tsa polasetiki tse tsamaisang mocheso, liphutheloana tsa semiconductor le ho tlatsa, liphutheloana tsa mocheso oa LED, joalo-joalo. liindasteri tsa nitride.

Liindasteri tse ling tseo ka tloaelo li ruang molemo ho li-ceramics tsa hexagonal boron nitride li kenyelletsa:

● Sepakapaka

● Ho theha tšepe

● Lisebelisoa tsa elektronike

● Ho futhumatsa le ho Pholisa

● Ho Etsa Khalase
