Ingcaciso yeMveliso

IBoron nitrideyenziwe yinitrogen kunye ne-athom zeboron kwikristale, ubume bekristale bunokwahlulwa ibe: i-hexagonal boron nitride (HBN), imiqolo eshinyeneyo ye-boron nitride enehexagonal kunye ne-cubic boron nitride, ukwakheka kwekristale ye-boron nitride enehexagonal inesakhiwo esifanayo segraphite. , ikhululekile, i-lubrication, ukufunxa lula ukufuma, ukukhanya kunye nezinye iimpawu zomgubo omhlophe, yithi kwakhona "igraphite emhlophe. Uxinaniso lwethiyori: 2.27g / cm3, ubunzima obuthile: 2.43, ubunzima be-mossberg: 2.

I-Hexagonal boron nitride ine-insulation elungileyo yombane, i-thermal conductivity, ukuzinza kweekhemikhali, akukho ndawo icacileyo yokunyibilika, ukumelana nobushushu ukuya kuthi ga kwi-3000 ℃ kwi-0.1 MPA nitrogen, kwindawo engathathi hlangothi yokunciphisa, ukumelana nobushushu ukuya kuthi ga kwi-2000 ℃, i-nitrogen kunye ne-argon isetyenziswa. kwiqondo lobushushu linokufikelela kwi-2800 ℃, uzinzo olulambathayo kwi-atmosfera ye-oxygen, ubushushu obungaphantsi kwe-1000 ℃. I-coefficient yokwandiswa kwe-boron nitride ilingana naleyo yequartz, kodwa i-thermal conductivity iphezulu ngokuphindwe kashumi kune-quartz. Kwiqondo lobushushu eliphezulu likwanayo nokuthambisa okulungileyo, lubricant eqinileyo yobushushu obuphezulu, inomthamo owomeleleyo wokufunxa ineutron, uzinzo kwiikhemikhali, phantse zonke iintsimbi ezityhidiweyo zinemichiza engasebenziyo.

I-hexagonal boron nitride enganyibilikiyo emanzini abandayo, i-hydrolysis yamanzi abilayo icotha kakhulu kwaye ivelise inani elincinci le-boric acid kunye ne-ammonia, kunye ne-asidi ebuthathaka kunye nesiseko esomeleleyo kwiqondo lobushushu begumbi alisebenzi, linyibilika kancinane kwi-asidi eshushu, kunye ne-sodium hydroxide etyhidiweyo, i-potassium. unyango lwe-hydroxide lunokubola. Inokumelana ne-corrosion efanelekileyo kuzo zonke iintlobo ze-asidi ye-inorganic, i-alkali, isisombululo setyuwa kunye ne-solvent ye-organic.

Isicelo

1, i-boron nitride ayinayo ityhefu, ukuxhathisa ubushushu obuphezulu, ukuxhathisa ukubola, i-thermal ephezulu.

i-conductivity, ukugquma okuphezulu, ukusebenza kakuhle kwe-lubrication yezinto.

2. Akuyona kuphela i-insulator yombane kodwa kunye nomqhubi we-thermal, i-electrolysis ekhethekileyo kunye

izinto zokuxhathisa kwiqondo lokushisa eliphezulu, i-insulator yombane ophezulu kunye nombane ohamba rhoqo

kunye ne-plasma arc.

I-3, ingasetyenziswa njenge-semiconductor eqinile-isigaba se-doped material, i-anti-oxidation okanye igrisi enganyangekiyo emanzini.

4. Ukushisa okuphezulu kwe-lubricant kunye ne-ejenti yokukhululwa kwe-mold, i-boron nitride powder nayo ingasetyenziswa njenge

i-anti-adhesion agent ye-glass beads, i-ejenti yokukhulula i-mold yeglasi kunye nokwenza isinyithi.

5. Izinto ezinzima kakhulu ezicutshungulwa yi-boron nitride zingenziwa kwizixhobo zokusika ngesantya esiphezulu

kunye namanqatha okugrumba ukuphononongwa kwejoloji kunye nokugrumba ioli.

6. Izixhobo zesakhiwo seeathom zeathom, imilomo yenqwelomoya kunye neenjini zerokethi, izinto zokupakisha.

ukuthintela ukusasazeka kwemitha ye-neutron, kunye nezixhobo zokukhusela i-thermal kwi-aerospace.

I-7, i-non-toxic kwaye ingenabungozi kunye ne-lubricity, ingasetyenziswa njenge-cosmetic filler.

8. Ngokuthatha inxaxheba kwe-catalyst, inokuguqulwa ibe yi-cubic boron nitride eqinile njengedayimane.

emva kokushisa okuphezulu kunye noxinzelelo lonyango.

I-9, yenza iintlobo ngeentlobo zefilimu ye-capacitor ye-aluminium yokubeka, i-tube yomfanekiso we-aluminium yokubeka, umboniso we-aluminium,

ezifana nesikhephe somphunga.

I-10, itywina lobushushu be-transistor desiccant kunye ne-resin yeplastiki kunye nezinye izongezo zepolymer.

I-11, zonke iintlobo ze-laser anti-counterfeiting aluminium plating, i-trademark ye-bronzing materials, zonke iintlobo zeelebhile zecuba, iileyibhile zebhiya, iibhokisi zokupakisha, iibhokisi zokupakisha ze-cigarette i-aluminium plating njalo njalo.
