Iimbonakalo:
IBoron ikwindawo ekhethekileyo phakathi kwesinyithi kunye ne-nonmetal kwitheyibhile yezinto ezijikelezayo. Iipropati zayo zekhemikhali zisebenza ngakumbi ngenxa yombane onamandla kakhulu ongenamandla, i-atomic radius encinci kunye ne-centralized nuclear charge. Izinzile kubushushu obuqhelekileyo, iyanyibilikiswa xa ifudunyezwa ukuya kwi-300℃, kwaye iyatshiswa ukuba ifudunyezwa ukuya kwi-700℃. Ayinancasa kwaye ayinavumba. Ipropati yayo engeyometal ifana nesilicon. IBoron inokunxibelelana neoksijini, initrogen, isalfure, ihalogen okanye ikhabhoni njl. Ingadityaniswa ngokuthe ngqo neentlobo ezininzi zeesinyithi ukwenza iikhompawundi zeboronic. Ngaphezu koko, iboron ingaphendulwa neekhompawundi ze-organic ukuvelisa ezinye iikhompawundi, apho iboron idityaniswa ngqo nekhabhoni, okanye ioksijini ikhona phakathi kweboron nekhabhoni.
Izicelo:
I-Boron isetyenziswa kakhulu kwi-metallurgy, kwi-elektroniki, kumayeza, kwiiseramikhi, kushishino lwe-nulear nakwishishini leekhemikhali njl.njl., isetyenziswa ngendlela ye-compound okanye yongezwa kwezinye ii-alloys njenge-add-andend. Ingasetyenziswa ekunyibilikiseni ezinye iintsimbi ze-alloy ezikhethekileyo kwaye njenge-gas remover yentsimbi enyibilikayo, kwi-burn-entraining pole ye-burning-entraining tube kushishino, kwi-control stick ye-atomic reactor, nakwi-high-energy fuels ze-rocket. Yinto ebalulekileyo yokwenza ii-halogenatedborons ezicocekileyo kakhulu, ikwayimpahla yokwenza iintlobo ngeentlobo zee-boronic compounds. Iimetal ezininzi ezintle nezinqabileyo zinokuthathelwa indawo kwaye zisindiswe yiyo. I-Boron kunye nee-compounds zayo zingasetyenziswa njenge-catalyst ye-organic chemical reactions, njalo njalo.
Iphakheji:
Ifakwe i-vacuum kwiingxowa ze-aluminium foil, apho kufakwe khona ingxowa yeplastiki.
Ubunzima obupheleleyo yi-1kg ngebhegi, i-5kg ngebhokisi, i-10kg ngebhokisi, i-25kg ngebhokisi
Indawo yokugcina:
Ifanele igcinwe kwindawo yokugcina emthunzini, engenisa umoya kwaye eyomileyo. Ixesha layo lokugcinwa limalunga nonyaka omnye.
Imveliso ingasetyenziswa ukuba isemgangathweni xa ivavanywa kwakhona emva komhla ochaziweyo.
Amanqaku okhuseleko:
Le mveliso ithathwa njengetyhefu xa uyiphefumla kwaye uyitya, ukuyiphefumla kuya kuba nefuthe kwinkqubo yemithambo-luvo ephakathi, ukuyitya kuya kukhokelela ekuvuseleleni isisu namathumbu, ubuthi bemijelo kunye ne-boron, ukudibana nolusu okanye amehlo kuya kukhokelela ekuvuselelekeni okuncinci, kufuneka unxibe iiglasi zokhuseleko, imaski ye-gauze engangeni luthuli, iiglavu zerabha xa uyiphatha.
