Yakachena kuchena hexagonal boron nitride poda cas 10043-11-5

Tsananguro Pfupi:

Boron nitride yakaumbwa nenitrogen uye boron maatomu mukristaro,
chimiro chekristaro inogona kukamurwa kuita: hexagonal boron nitride (HBN), mitsara yakaoma ye hexagonal boron nitride uye cubic boron nitride, iyo kristaro chimiro che hexagonal boron nitride ine yakafanana graphite dhizaini dhizaini, yakasununguka, lubrication, nyore kutora mwando, mwenje uye humwe hunhu hwechena
upfu, taura zvekare saka “white graphite.

Boron nitride inoumbwa nenitrogen uye boron maatomu mukristaro, iyo kristaro chimiro inogona kukamurwa kuita:

hexagonal boron nitride (HBN), mitsara yakaoma ye hexagonal boron nitride uye cubic boron nitride, iyo kristaro

Chimiro chehexagonal boron nitride ine yakafanana graphite layer chimiro, yakasununguka, lubrication, nyore kutora

yehunyoro, mwenje uye humwe hunhu hwehupfu chena, taura zvakare saka "chena graphite. Yehunyanzvi kuwanda: 2.27g / cm3,

yakananga giravhiti: 2.43, mossberg kuomarara: 2. Hexagonal boron nitride iri ine yakanaka magetsi kuputira,

kudziya kwekupisa, kugadzikana kwemakemikari, hapana iko kunonyungudika kuri pachena, kupisa kupisa kusvika 3000 ℃ mu01 MPA nitrogen,

mune yekusarerekera kudzora mhepo, kupisa kupisa kusvika 2000 ℃, iyo nitrogen uye argon inoshandiswa mune tembiricha

Inogona kusvika 2800 ℃, isina kugadzikana mumhepo oxygen, tembiricha pazasi pe1000 ℃. Iko kuwedzera kwekuwedzera kwe

boron nitride yakaenzana neiyo yequartz, asi iyo yekushisa inoitisa yakapetwa kagumi kupfuura iyo quartz.

Pane yakanyanya tembiricha inewo mafuta akanaka, yakanaka yakanaka tembiricha yakasimba mafuta, ine neutron yakasimba

hunyoro hwekugona, makemikari kugadzikana, angangoita ese esimbi yakanyungudutswa ane makemikari inertness.

Hexagonal boron nitride insoluble mumvura inotonhorera, mvura irikufasha hydrolysis inononoka uye inogadzira shoma

ye boric acid neammonia, uye isina simba asidhi uye yakasimba base mukamuri tembiricha haina kugadzikana, inogadzikana zvishoma

mune inopisa asidi, ine yakanyungudutswa sodium hydroxide, potassium hydroxide kurapwa inogona kuora. Izvo zvine zvakanaka

ngura kuramba kumarudzi ese eorganic acid, alkali, mhinduro yemunyu uye organic solvent.

Kushanda

1, boron nitride ndeye isina-chepfu, yakanyanya tembiricha kuramba, ngura kuramba, yakanyanya kupisa

kuitisa, kukwirisa kwakanyanya, kugona kwekugadzirisa kwezvinhu.

2. Haisi chete insulator yemagetsi asiwo conductor inopisa, yakasarudzika electrolysis uye
kuramba zvinhu pakukwirira tembiricha, insulator yemagetsi akakwirira uye yakakwira frequency magetsi
uye plasma arc.

3, inogona kushandiswa se semiconductor solid-phase doped zvinhu, anti-oxidation kana isina mvura girisi.

4. Huru yekushisa girisi uye muforoma kuburitsa mumiririri, boron nitride poda inogona zvakare kushandiswa se
anti-adhesion mumiriri wegirazi mabhesi, chakuvhuvhu kuburitsa mumiririri wegirazi nesimbi inogadzira.

5. Iyo yakaoma-yakaoma zvinhu zvakagadziriswa ne boron nitride inogona kugadzirwa mune yekumhanyisa-kukurumidza maturusi ekushandisa
uye kuchera matimu ekuongorora kweiyo geological uye kuchera kwemafuta.

6. Zvivakwa zveatomiki maactor, mhezi dzendege uye rocket injini, zvekutakura zvinhu
kudzivirira radiation neutron radiation, uye yekupisa yekudzivirira zvinhu muaerospace.

7, isiri-chepfu uye isina njodzi uye lubricity, inogona kushandiswa seyekuzadza mafirita.

8. Nekutora chikamu kwekubatsira, inogona kushandurwa kuita cubic boron nitride yakaoma sedhaimani
mushure mekushisa kwakanyanya uye kumanikidza kurapwa.

9, ita akasiyana capacitor firimu aluminium yakanamirwa pamifananidzo, mufananidzo chubhu aluminium yakanamirwa pamifananidzo, aruminiyamu kuratidza,
dzakadai semhepo yekupuka.

10, transistor kupisa chisimbiso desiccant uye epurasitiki nebwe uye mamwe ma polymer ekuwedzera.

11, ese marudzi e-laser anti-manyepo aruminiyamu yakanamirwa pamifananidzo, chiratidzo chekutengesa bronzing zvinhu, ese marudzi emafabheti zvinyorwa, zvinyorwa zvebhiya, mabhokisi ekupakata, emidzanga ekuputira mabhokisi aruminiyamu raiti nezvimwewo.
