Chaw tsim tshuaj paus zoo B2O3 boron oxide hmoov cas 1303-86-2
Boron oxide yog cov xim tsis muaj iav siv lead ua los yog hmoov. Qhov zoo yog tawv thiab nkig, lub sufrace yog du
thiab qab. Nws yog thermally ruaj khov thiab yuav tsis raug txo los ntawm carbon thaum nws yog incandescent, tab sis alkali hlau, magnesium thiab txhuas tuaj yeem txo nws mus rau monomer boron. Thaum txog 600 ℃, Nws dhau los ua ib qho heev
kua nplaum. Boric acid anhydride tuaj yeem nqus dej hauv huab cua kom tsim tau boric acid. Nws yog soluble
hauv acid, ethanol, dej kub, thiab me ntsis soluble hauv dej txias. Boron oxide tuaj yeem ua ke nrog ntau cov hlau oxides los ua iav nrog cov yam ntxwv xim. Nws yog tag nrho miscible nrog alkali hlau, tooj liab,
Sliver, lead, arsenic, antimony, thiab bismuth oxides.
Qhov ceev ntawm crystalline boron oxide yog 2.46g / cm3, qhov ceev ntawm amorphous boron oxide yog 1.80 ~ 1.84g / cm3, melting point 557 ℃, solubility g / 100gH2O: 1.1 (0 ℃), 15.7 (100 ℃ dej) , ua
turbid tom qab nqus dej noo, thiab tuaj yeem yaj hauv cawv.
Thaum qhov kub thiab txias, H3BO3 lub cev qhuav dej tuaj yeem tsim cov boron trioxide crystals, Cov siv lead ua no muaj BO4 tetrahedral structural unit, ntom 1.805g / cm3, melting point 450 ℃, Qhov ntom ntawm iav boron oxide.
yog 1.795g / cm3, thiab nws maj mam softens thaum kub nce, thiab ua kua thaum nws mus txog lub kub kub kub, nrog ib tug boiling point ntawm 1500 ℃. Boron thiab oxygen tau ncaj qha ua ke kom muaj B2O3.
