(Budada boron)
Boron, dhinac 5 miiska walxaha, Waxay ka jirtaa noocyo badan oo allotropic ah, leh budo crystalline iyo amorphous ah oo ah kuwa ugu warshadaha ku habboon.
Crystalline boron guud ahaan waxay qaadataa qaab-dhismeedka rhombohedral (α-rhombohedral) oo ka kooban B₁₂ icosahedra oo ku xidhan shabakad saddex-cabbir ah oo adag, muujinta adkeysi sare, ilaalinta kulaylka, iyo falalka semiconductor.
Taas bedelkeeda, boron amorphous ah ma laha nidaamka atomiga ee fog, oo ay ku jiraan rucubyo khalkhalsan oo atomyada boron ah kuwaas oo keena dareenka kiimikaad sare taas oo ka dhalatay curaarta laadlaadsan iyo dhibaatooyinka dhismaha.
Amorphous boron guud ahaan waxa lagu abuuraa hoos u dhac kiimikaad ee boron halides ama kulaylka kuleyl ee boron hydrides, soo saarida budo yaryar oo leh cabbirro qaybo u dhexeeya nanometers ilaa micrometers.
Boron amorphous nadiif ah oo sarreeya (> 95% B) waxay muhiim u tahay codsiyada cusub, sida wasakhowga sida ogsijiinta, kaarboon, iyo biraha ayaa si weyn u bedeli kara dhaqdhaqaaqa gubashada, dhismayaasha korontada, iyo hawsha kicinta.
Dabeecadda dheef-shiid kiimikaadka boron-ka-soo-baxa ah waxay ka dhigtaa mid u nugul crystallization heerarka heerkulka sare (dhaaftay 800 ° C), Kaas oo laga faa'iidaysan karo ama la dhimi karo iyadoo ku xidhan isticmaalka la qorsheeyay.
1.2 Muuqaalka Jirka iyo Elektarooniga ah
Budada boron, gaar ahaan qaab amorphous ah, soo bandhig guryo gaar ah oo la degan yahay ama ganacsi oo ka imanaya dabeecadooda elektarooniga ah iyo isku xidhka xarumaha badan.
Waxay leeyihiin arrin dhalaalaysa oo sarreeya (agagaarka 2076 ° C ee boron crystalline) iyo adkeysi aad u wanaagsan (labaad oo kaliya in ruby iyo boron nitride cubic), iyaga oo ka dhigaya kuwo ku habboon dhammaystirka xidhashada u adkaysta iyo xoqidda.
Amorphous boron waxay leedahay faashad qiyaas ah 1.5– 1.6 eV, dhex dhexaad u ah biraha iyo insulators, taas oo suurtogal ka dhigaysa caadooyinka semiconductor-ka la mid ah oo leh habdhaqan la hagaajin karo iyada oo loo marayo doping ama naqshadaynta dhibka.
Dhumucdiisu hooseeyso (2.34 g/cm LABA) waxay hagaajisaa waxqabadka nidaamyada tamarta-fudud, halka ay faahfaahinta sare ee nuxurka tamarta (~ 58 kJ/g marka uu oksaydhisku ku jiro) wuu dhaafaa gaaska caadiga ah ee tirada badan.
Tilmaamahani waxay dejinayaan budada boron sida alaabooyin badan oo tamar ah, qalabka elektarooniga ah, iyo codsiyada naqshadaha.

2. Hababka Synthesis iyo Wax soo saarka Warshadaha
2.1 Soo saarista Boron Amorphous
Mid ka mid ah habka ugu caansan ee abuurista boron-ka-soo-baxa waa yaraynta boron trichloride (BCl saddex) oo leh hydrogen heerkul dhexdhexaad ah (600– 800 ° C) ee firfircooni sariirta dareeraha leh.
Habkani waxa uu abuuraa budo madow ama brownish ah oo ka kooban nanoparticles la isku daray, Kaaso markaas lagu sunmeeyo iyada oo la isticmaalayo dheecaan aashito ah si looga takhaluso chlorides soo noqnoqda iyo wasakhowga birta.
Kooras ka duwan waxaa ka mid ah kala-goynta kulaylka ee diborane (B ₂ H₆) heerkulka hoose, soo saarida boron ultrafine amorphous leh oo leh dhul sare, inkastoo habkani uu yahay mid aan la qiyaasi karin sababtoo ah qiimaha sare iyo xasilloonida horudhacyada borane.
Dheeraad ah dhawaan, hoos u dhaca magnesium ee B TWO O two ayaa dhab ahaantii loo helay hab la awoodi karo, inkasta oo ay ku baaqayso hab-socodka ka dib si taxadar leh si looga takhaluso natiijooyinka MgO oo loo gaaro nadiif sare.
Kooras kasta oo isku dhafan ayaa bixiya tanaasul inta u dhaxaysa wax-soo-saarka, daahirnimo, xoogaa morphology ah, iyo qiimaha wax soo saarka, saamayn ku leh doorashada codsiyada gaarka ah.
2.2 Naqshadeynta iyo Naqshadeynta Qaybaha
Sifeynta ka-daba-ku-jirku waa muhiim si kor loogu qaado waxqabadka, gaar ahaan codsiyada tamarta iyo dhijitaalka ah ee wasakhdu u shaqeyso sida ka hortagga falcelinta ama dabinnada.
Hydrofluoric iyo hydrochloric acid daawaynta waxay si sax ah u milaan oxide iyo wasakhowga birta, halka kulaylka kuleylku ku soo qulqulayaan degaannada aan firfircoonayn waxay xitaa aad u yareyn kartaa nuxurka oksijiinta waxayna dejin kartaa qaab-dhismeedka amorphous.
Baaxadda walxaha hoos u dhaca iyada oo la adeegsanayo wax-shiidka wareega ama wax-shiididda jet-ku waxay ogolaataa tollida dusha iyo falcelinta, in kasta oo shiididda xad dhaafka ah laga yaabo in ay keento samayn hore ama faddarayn ka timaada warbaahinta shiida.
Farsamooyinka xajinta dusha sare, sida daboolida polymers ama oksaydhyada, waxaa loo shaqeeyaa si ay u joojiyaan oksaydheynta kediska ah inta lagu jiro goobta kaydinta iyadoo la ilaalinayo dareenka xaaladaha shilalka la kantaroolay.
