Chaw tsim khoom zoo B2O3 boron oxide hmoov cas 1303-86-2
Boron oxide yog ib qho siv lead ua los yog hmoov tsis muaj xim. Qhov zoo yog tawv thiab brittle, lub sufrace yog du
thiab tsis muaj saj. Nws ruaj khov thiab yuav tsis raug txo los ntawm cov pa roj 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 nplaum. Boric acid anhydride tuaj yeem nqus dej hauv huab cua kom tsim tau boric acid. Nws yaj tau
nyob rau hauv cov kua qaub, ethanol, dej kub, thiab me ntsis soluble nyob rau hauv dej txias. Boron oxide tuaj yeem ua ke nrog ntau cov hlau oxides los tsim cov iav nrog cov xim yam ntxwv. Nws yog miscible tag nrho nrog alkali hlau, tooj liab,
Cov hlau oxides xws li hlau daj, hlau txhuas, hlau arsenic, hlau antimony, thiab hlau bismuth.
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 ℃) Yooj yim nqus dej, ua
nws turbid tom qab nqus cov dej noo, thiab kuj tuaj yeem yaj hauv cawv.
Thaum qhov kub qis, H3BO3 dehydration tuaj yeem tsim cov boron trioxide crystals, Cov crystal no muaj BO4 tetrahedral structural unit, qhov ceev 1.805g / cm3, melting point 450 ℃, Qhov ceev ntawm glassy boron oxide
yog 1.795g/cm3, thiab nws maj mam mos thaum qhov kub nce, thiab ua kua thaum nws mus txog qhov kub liab siab, nrog rau qhov kub npau ntawm 1500 ℃. Boron thiab oxygen tau sib xyaw ua ke ncaj qha kom muaj B2O3.
