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 faʻapipiʻi maualuga, faʻafefiloi vaega mautu mo semiconductor, mea faʻapipiʻi mo atomic reactors, faʻamalama faʻapipiʻi mea faʻapipiʻi e puipuia ai le afi afi, faʻamalama faʻamalama faʻapipiʻi, mea faʻapipiʻi afi e puipuia ai le afi afi, faʻamalama faʻamalama, faʻapipiʻi mea faʻapipiʻi e puipuia ai le afi afi. vaega. 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.
