Boron nitride CAS 10043-11-5
Boron nitride o se tioata e aofia ai atoms nitrogen ma atoms boron. O le fausaga tioata ua vaevaeina i nitride boron hexagonal (HBN), nitride boron hexagonal latalata (WBN) ma nitride boron cubic. O le fausaga tioata o le hexagonal boron nitride o loʻo i ai se fausaga faʻapipiʻi tutusa o le graphite, o loʻo faʻaalia ai se matala, lubricated, susu-absorbing, malamalama paʻepaʻe paʻepaʻe, o lea e taʻua ai foi o le "graphite paʻepaʻe". O le faʻaopoopoga faʻaopoopoga o le hexagonal boron nitride e tutusa ma le quartz, ae o le faʻauluina o le vevela e faʻasefulu taimi nai lo le quartz. E iai fo'i le lubricity lelei i le vevela maualuga ma o se lubricant mautu maualuga maualuga ma malosi malosi fa'afefete neutron, mea tau vaila'au mautu, ma le inertness vaila'au i toetoe lava o metala u'amea uma. Hexagonal boron nitride e le mafai ona solu i le vai malulu. A fa'apuna le vai, e fa'asusu lemu ma maua mai ai sina vaega itiiti o le boric acid ma le ammonia. E le tali atu i mea vaivai vaivai ma faavae malosi ile vevela ole potu. E solu teisi i le ga'o vevela ma e na'o le togafitiina o le sodium hydroxide ma le potassium hydroxide e mafai ona pala. O lo'o i ai le malosi tele o le fa'a'ele'ele i vaila'au fa'aletino eseese, alkalis, vaifofo masima ma solvents organic.

1. Boron nitride o loʻo faʻaaogaina e fai ai mea faʻafefete, mea faʻapipiʻi ogaumu, ma faʻaaogaina foi i mea tau eletise, masini, vaalele ma isi pisinisi.
2. Boron nitride o loʻo i ai le tele o mea sili ona lelei ma e faʻaaogaina lautele i insulators mo le maualuga-voltage ma le maualuga o le eletise ma le plasma arcs, faʻapipiʻi mo le faʻapipiʻiina otometi faʻavaa vevela maualuga, mea mo afi faʻaoso maualuga, faʻafefiloi vaega mautu mo semiconductor. , mea faʻapipiʻi mo faʻaola atomika, mea faʻapipiʻi e puipuia ai le neutron radiation, faʻamalama faʻafeiloaʻi radar, faʻasalalauga antenna radar ma vaega afi afi. Ona o lona lelei lubricating meatotino, e faʻaaogaina e avea o se lubricant maualuga-vevela ma se sui demoulding mo faʻataʻitaʻiga eseese. E mafai ona fa'aogaina le boron nitride e fai ai ni u'amea e tete'e i le vevela ma isi oloa. E mafai ona fa'aaogaina e fai ma mea e sili ona malosi, talafeagai mo su'esu'ega fa'afanua, vili vili suau'u ma mea faigaluega tipi saosaoa. E mafai foʻi ona faʻaaogaina e avea o se mea faʻapipiʻi uʻamea, faʻatasi ai ma uiga o le maualalo o le gaosiga o le vevela ma nai mea faʻaletonu o vaega. Boron nitride e mafai foi ona faʻaaogaina e fai ma faʻaopoopoga mo mea eseese. Boron nitride alava faia mai le boron nitride o se alava medium-modulus maualuga-galuega aoga. O se mea fa'ainisinia fa'ainisinia e mafai ona fa'aaogaina lautele i le vaila'au vaila'au, fale ie, tekinolosi aerospace ma isi vaega o alamanuia fa'atauva'a.
3. Fa'asa'oloto sui mo u'amea fau ma lubricant mo uaea ata tusi; fa'apitoa fa'aeletise ma mea fa'atete'e i lalo ole vevela maualuga; lubricant malo; desiccant fa'amaufa'ailoga vevela mo transistors ma fa'aopoopo mo polymers e pei o resini palasitika; boron nitride oloa oomi i foliga eseese e mafai ona faʻaaogaina e pei o le maualuga o le vevela, maualuga o le mamafa, faʻapipiʻi ma vaega faʻafefe vevela; mea e puipuia ai le vevela i totonu o le alamanuia aerospace; faatasi ai ma le auai o catalysts, e mafai ona liua i nitride boron kupita e pei o le taimane pe a uma le vevela maualuga ma togafitiga maualuga.
