ANTIMONY (IV) OXIDE CAS 1332-81-6 yog dab tsi?

Antimony oxide yog cov hlau oxide tsim los ntawm antimony thiab cov pa oxygen, feem ntau suav nrog antimony trioxide (Sb2O3) thiab antimony pentoxide (Sb2O5). Antimony trioxide zoo li cov hmoov dawb crystalline hmoov. Nws tig daj thaum rhuab thiab dawb thaum txias. Tsis hnov tsw. Tus txheeb ze ntom ntom: 5.67. Melting point: 655 ℃. Kub taw tes: 1425 ℃. Nws tuaj yeem sublimate thaum rhuab mus rau 400 ℃ hauv qab lub tshuab nqus tsev siab. Nws yog soluble hauv sodium hydroxide tov, kub tartaric acid tov, tartrate hydrogen ntsev tov thiab sodium sulfide tov, thiab me ntsis soluble nyob rau hauv dej, dilute nitric acid thiab dilute sulfuric acid. Antimony pentoxide tshwm raws li lub teeb daj hmoov, yog insoluble nyob rau hauv dej, me ntsis soluble nyob rau hauv alkali, thiab muaj peev xwm tsim antimonate.
