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

Boron nitride ndi kristalo wopangidwa ndi maatomu a nayitrogeni ndi ma atomu a boron. Kapangidwe ka kristalo kumagawidwa kukhala hexagonal boron nitride (HBN), yodzaza ndi hexagonal boron nitride (WBN) ndi kiyubiki boron nitride. Mapangidwe a kristalo a hexagonal boron nitride ali ndi mawonekedwe ofanana ndi ma graphite, omwe amawonetsa kutayirira, mafuta, kuyamwa kosavuta kwa chinyezi, kulemera kopepuka ndi zilembo zina za ufa woyera, motero amatchedwanso "white graphite".

Theoretical density 2.27g/cm3, mphamvu yokoka yeniyeni: 2.43, Mo kuuma ndi 2.

Hexagonal boron nitriding ali kutchinjiriza wabwino magetsi, madutsidwe matenthedwe, bata mankhwala, palibe zoonekeratu malo osungunuka, kutentha kukana mu 0.1MPA asafe kuti 3000ºC, mu ndale kuchepetsa mpweya, kutentha kukana 2000ºC, asafe ndi argon ntchito kutentha kufika 2800ºC, mu mpweya mpweya bata ndi osauka, ntchito kutentha m'munsimu 1000ºC.

Hexagonal boron nitride ili ndi coefficient yofanana yowonjezera monga quartz, koma matenthedwe ake amatenthedwa kuwirikiza kakhumi kuposa quartz. Ilinso ndi mafuta abwino pa kutentha kwakukulu, ndi mafuta abwino kwambiri otenthetsera kutentha kwambiri, imakhala ndi mphamvu yamphamvu ya mayamwidwe a nyutroni, kukhazikika kwa mankhwala, ndipo imakhala yosasunthika ndi zitsulo zonse zosungunuka.

Hexagonal boron nitriding madzi ozizira osasungunuka, madzi otentha hydrolysis ndi wodekha kwambiri ndi kutulutsa pang'ono boric acid ndi ammonia, ndi asidi ofooka ndi amphamvu m'munsi pa firiji sachita kanthu, pang'ono sungunuka mu otentha asidi, ndi wosungunuka sodium hydroxide, potaziyamu hydroxide. mankhwala kuwola. Lili ndi dzimbiri kukana zosiyanasiyana inorganic zidulo, maziko, mchere zothetsera ndi organic solvents.

● Kusamva kutentha

● Kusamva mankhwala

● Mosakhazikika ndi mankhwala

● Low matenthedwe madutsidwe

● Kuwonjezeka kwa kutentha kochepa

● Low dielectric constant

● Kusanyowetsa (magalasi, mchere, zitsulo zina)

● Kudzipaka mafuta

● Zopangidwa mosavuta

● Kuteteza magetsi

Zina mwazodziwika bwino za boron nitride zomwe timamaliza ndi:

● Zothandizira ndi zida za ng'anjo

● Zotengera zosungunulira magalasi ndi zitsulo

● Plasma ndi kuwotcherera nsonga insulators

● Kutentha kwapamwamba kwambiri

● Mipope yonyamula zitsulo yosungunuka

● Zishango za zida za nyukiliya ndi zomangira

● Zophatikizika za semiconductor

● Zitsamba za ceramic

● Kuteteza kutentha kwa ma radiation

● Makina ochapira a ceramic

● Makina otentha a transistor

● Zolinga zamwano

● Zoteteza magetsi ku Ceramic

● Mabwato

● Zoteteza ku thermocouple

Hexagonal boron nitride ndi mtundu wapamwamba kwambiri wa ceramic. Kapangidwe kake kakang'ono ndi kosalala ndipo kapangidwe kake ka maselo ndi hexagonal crystal. Hexagonal boron nitride ili ndi zida zapadera komanso zabwino kwambiri zakuthupi ndi zamankhwala. Ili ndi ma conductivity abwino kwambiri amafuta, kutchinjiriza kwamagetsi, kukana kwa dzimbiri kwa mankhwala komanso kukana kwa okosijeni. Imatha kupirira mpaka 1000OC mumlengalenga, mpaka 2000OC mu mpweya wopumira ndi vacuum. crystalline boron nitride yakhala ikugwiritsidwa ntchito pa kutentha kwakukulu kwa 2000OC, yokhala ndi mankhwala okhazikika ndi thupi komanso matenthedwe abwino kwambiri (kutentha kwa kristalo imodzi kuli pafupi 250-300W / mk). Pakalipano, kampaniyo imapanga ufa wa crystalline wa flake wokhala ndi kukula kwa kristalo wa 500 nanometer-20 microns ndi nanoscale spherical boron nitride.

Hexagonal boron nitride imayamikiridwa ndi makampani amagetsi chifukwa chosowa kwambiri matenthedwe matenthedwe komanso magwiridwe antchito amagetsi. Opanga zamagetsi apakhomo ndi akunja achita kafukufuku wamkulu wamapulasitiki opangira matenthedwe, kuyika kwa semiconductor ndi kudzaza, ma CD otulutsa kutentha kwa LED, ndi zina zambiri. Zimagwira ntchito bwino pakusungunula zitsulo zachikhalidwe, kuponyera, mafuta apadera opaka mafuta, makampani agalasi ndi boron zina. mafakitale a nitride.

Makampani ena omwe nthawi zambiri amapindula ndi hexagonal boron nitride ceramics ndi awa:

● Zamlengalenga

● Kupanga zitsulo

● Zamagetsi

● Kutentha ndi Kuziziritsa

● Kupanga Magalasi

● Asilikali ndi Chitetezo

● Thermal Processing
