Ingcaciso yeMveliso

I-boron oxide yikristale okanye umgubo ongenambala weglasi. Umgangatho wayo uqinile kwaye uyaphuka, i-sufrace ithambile

kwaye ayinancasa. Izinzile kubushushu kwaye ayizukuncipha yikhabhoni xa ishushu, kodwa ii-alkali metals, i-magnesium kunye ne-aluminium zonke zinokunciphisa zibe yi-monomer boron. Malunga ne-600℃, iba yi-high high kakhulu.

ulwelo oluqinileyo. I-anhydride ye-boric acid inokufunxa amanzi emoyeni ngamandla ukuze ivelise i-boric acid. Iyanyibilika

kwi-asidi, i-ethanol, amanzi ashushu, kwaye inyibilika kancinci emanzini abandayo. I-boron oxide inokudityaniswa nee-metal oxides ezininzi ukwenza iglasi enemibala eyahlukileyo. Ingaxutywa ngokupheleleyo nee-alkali metals, i-copper,

I-Sliver, i-lead, i-arsenic, i-antimony, kunye ne-bismuth oxides.

Uxinano lwe-crystalline boron oxide yi-2.46g/cm3, uxinano lwe-amorphous boron oxide yi-1.80 ~ 1.84g/cm3, iqondo lokunyibilika yi-557℃, ukunyibilika yi-g/100gH2O: 1.1(0℃), 15.7(100℃) Ukufunxa amanzi ngokulula, kube

Iyaguquguquka emva kokufunxa umswakama, kwaye inokunyibilika kwi-alcohol.

Xa ubushushu buphantsi, ukuphelelwa ngamanzi emzimbeni kwe-H3BO3 kunokuvelisa iikristale ze-boron trioxide, Le kristale iqulethe iyunithi yesakhiwo se-BO4 tetrahedral, uxinano lwe-1.805g/cm3, indawo yokunyibilika yi-450℃, Uxinano lwe-boron oxide yeglasi

yi-1.795g/cm3, kwaye ithamba kancinci kancinci xa ubushushu bunyuka, ize ibe lulwelo xa ifikelela kubushushu obubomvu obuphezulu, kunye neqondo lokubila le-1500℃. I-Boron kunye ne-oxygen zidityaniswe ngokuthe ngqo ukuze zibe ne-B2O3.
