Boron Nitride Crucible BN Crucible
Tohutohu Hua
Ko te Boron Nitride, e mohiotia ana ko BN, Hexagonal Boron Nitride (H-BN), me te Boron Nitride wera-wera, he mea tino pai ki te whakahinuhinu-whaiaro ka taea te tu atu i te wera nui me te pupuri i tona kaha whakahinuhinu i roto i te taiao korehau teitei.He mea hanga nga parapara Boron Nitride a AEM mai i te wera-pēhia boron nitride pātea.He rite te ahua o te Hexagonal Boron Nitride (H-BN) me te graphite ma te miihini engari he pai te aukati hiko., ka taea hoki te whakaputa hei hua whakamutunga BN pera i te ipu, poti, paninga, aha atu.
Nga waahanga matua
He pai te whakamaarama hiko o te Boron nitride, te kawe i te waiariki, te pumau matū, me te kore e kitea he rewa.Ko te nui o te whakamahinga o te pāmahana i roto i te 0.1MPA hauota ka tae ki te 3000 °C, i roto i te hau whakaheke koretake, ka taea e ia te tu atu i te wera ki te 2000 °C, me te paanga o te whakamahi i roto i te hauota me te argon ka tae ki te 2800 °C, me te pumau i roto i te hau o te hāora. he rawakore, a kei raro iho i te 1000 °C te pāmahana whakamahi.Ko te whakarea roha o te hexagonal boron nitride he rite ki tera o te quartz, engari ko te kawe werawera he tekau nga wa o te kiripaka.
I tua atu, karekau te boron nitride hexagonal e memeha i roto i te wai matao, a, ka kohuatia te wai, ka tino puhoi te hydrolysis me te whakaputa i te iti o te waikawa boric me te haukini.Karekau e tauhohe ki te waikawa ngoikore me te turanga kaha i te pāmahana rūma, he paku wairewa ki te waikawa wera, me mahi ki te konutai konutai rewa me te pāhare pāporo waihā kia pirau.

Tono Hua
Ko te Boron nitride he ahua o te teitei o te pāmahana, te aukati waikura, te wera nui o te waiariki, te whakamarumaru teitei me te pai o te mahi whakahinuhinu o te rauemi, ko te ahuatanga o naianei ki te whakangawari i te mahi, te whakaiti i nga utu whakaputa, te whakapai ake i te oranga o nga waahanga o naianei. te aronga rangahau o aua rauemi.
(1) Ma te whakamahi i te pai o te matū matū o te hexagonal boron nitride, ka taea te whakamahi hei parapara, poti, putorino tuku whakarewa wai, puha takirirangi, turanga taputapu mana-tiketike, pipeline whakarewa whakarewa, wahi papu, whakarewa whakarewa maitai, aha atu mo te whakarewa i nga konganuku whakaeto.
(2) Ma te whakamahi i te wera me te waikura o te nitride hexagonal boron nitride, nga waahanga teitei-te wera, nga papaa o te ruuma mura ahi, nga whakangungu wera mokowhiti, nga kaiwhakaputa magnetocurrent, me etahi atu ka taea te hanga.
(3) Ma te whakamahi i te whakamaarama o te nitride boron hexagonal, ka whakamahia nuitia i roto i te ngaohiko teitei-nui te hiko me te plasma arc insulators me te insulators o nga momo whakamahana, nga pupuhi ngongo whakawera me te teitei-te teitei, te teitei, te ngaohiko teitei me te nga waahanga whakamahana wera, me te whakamahi auau o nga rauemi oumu hiko.
