Yintoni iBoron nitride CAS 10043-11-5?

IBoron nitride yikristale eyenziwe ngeeathom zenitrogen kunye neeathom zeboron. Isakhiwo sekristale sahlulwe kwi-hexagonal boron nitride (HBN), i-close-packed hexagonal boron nitride (WBN) kunye ne-cubic boron nitride. Ubume bekristale ye-hexagonal boron nitride inokwakheka okufanayo kwegraphite, ebonisa ukukhululeka, ukuthambisa, ukufunxa ukufuma, umgubo omhlophe okhanyayo, ke ikwabizwa ngokuba "yigraphite emhlophe". I-coefficient yokwandisa ye-hexagonal boron nitride ilingana ne-quartz, kodwa ukuhanjiswa kwe-thermal kuphindwe kashumi kune-quartz. Ikwanayo nokuthambisa okulungileyo kumaqondo obushushu aphezulu kwaye yeyona nto ibalaseleyo yobushushu obuphezulu bokuthambisa okuqinileyo kunye nesakhono sokufunxa senutroni eyomeleleyo, iipropati zekhemikhali ezizinzileyo, kunye nokungangeni kwemichiza phantse kuzo zonke iintsimbi ezityhidiweyo. I-hexagonal boron nitride ayinyibiliki emanzini abandayo. Xa amanzi ebilisiwe, i-hydrolyzes kancinane kwaye ivelisa isixa esincinci se-boric acid kunye ne-ammonia. Ayinakusabela nge-acids ebuthakathaka kunye neziseko ezinamandla kwiqondo lokushisa. Inyibilika kancinane kwi-asidi eshushu kwaye inokubola kuphela ngokunyanga nge-sodium hydroxide etyhidiweyo kunye ne-potassium hydroxide. Inokumelana nokukhula okukhulu kwiiasidi ezahlukeneyo ze-inorganic, iialkali, izisombululo zetyuwa kunye nezinyibilikisi eziphilayo.

Isicelo

1. I-Boron nitride isetyenziselwa ukwenza izinto eziphikisayo, izixhobo zokugquma isithando somlilo, kwaye zikwasetyenziswa kwizinto zombane, oomatshini, inqwelomoya kunye namanye amashishini.

2. I-Boron nitride ineempawu ezininzi ezigqwesileyo kwaye isetyenziswa ngokubanzi kwii-insulators ze-voltage ephezulu kunye ne-high-frequency umbane kunye ne-plasma arcs, ii-coatings ze-welding ngokuzenzekelayo iifreyimu ezinobushushu obuphezulu, izixhobo zokushisa eziphakamileyo eziphezulu, i-admixtures yesigaba esiqinileyo se-semiconductors. , izinto zesakhiwo se-athomu ye-athomu, izinto zokupakisha ukuthintela imisebe ye-neutron, iifestile zokudlulisa i-radar, imidiya ye-antenna ye-radar kunye namacandelo e-injini ye-rocket. Ngenxa yeempawu zayo zokuthambisa ezigqwesileyo, isetyenziswa njenge-lubricant yobushushu obuphezulu kunye ne-ejenti yokudiliza kwiimodeli ezahlukeneyo. I-boron nitride ebunjiweyo ingasetyenziselwa ukwenza ii-crucibles ezixhathisa ubushushu obuphezulu kunye nezinye iimveliso. Ingasetyenziselwa njengento enzima kakhulu, ifanelekile ukuhlola i-geological, i-oil drilling drill bits kunye nezixhobo zokusika ngesantya esiphezulu. Isenokusetyenziswa njengesixhobo sokugaya isinyithi, esineempawu zeqondo lokushisa eliphantsi lokulungiswa komhlaba kunye neziphene ezimbalwa zamacandelo. IBoron nitride isenokusetyenziswa njengesongezelelo sezinto ezahlukeneyo. Ifayibha yeBoron nitride eyenziwe ngeboron nitride yifiber ephakathi-modulus esebenza kakhulu. Yimathiriyeli yobunjineli bokwenziwa kwe-inorganic enokuthi isetyenziswe ngokubanzi kwishishini lemichiza, kwishishini lelaphu, itekhnoloji ye-aerospace kunye namanye amacandelo oshishino aphambili.

I-3.I-arhente yokukhupha i-metal forming kunye ne-lubricant ye-metal wire drawing; izinto ezikhethekileyo ze-electrolytic kunye nokumelana phantsi kobushushu obuphezulu; isithambiso esiqinileyo; i-desiccant ye-heat seal ye-transistors kunye ne-additive for polymers ezifana nee-resin zeplastiki; iimveliso ze-boron nitride ezicinezelwe kwiimilo ezahlukeneyo zingasetyenziswa njengobushushu obuphezulu, uxinzelelo oluphezulu, ukugquma kunye namacandelo okuphelisa ubushushu; izixhobo zokukhusela i-thermal kwishishini le-aerospace; ngokuthatha inxaxheba kwe-catalysts, inokuguqulwa ibe yi-cubic boron nitride enzima njengedayimane emva kokushisa okuphezulu kunye nonyango oluphezulu.
