72% min cobalt Tetroxide Co3O4
Cov ntaub ntawv tseem ceeb:
Cov mis mos molecular: Co3O4
2.Molecular hnyav: 240.797
CAS Nr .: 1308-06-1
4.Purity: Co: 72% min
5.Storage: Khaws lub receptacle kaw thiab khaws cia rau hauv qhov chaw txias thiab qhuav, thiab xyuas kom meej tias chav ua hauj lwm muaj qhov cua zoo los yog tso pa tawm.
Cobalt Tetroxide zoo ib yam li ferroferric oxide, thiab muaj peev xwm suav tau tias yog ib qho chaw tsim los ntawm cobalt oxide (CoO) thiab cobalt oxide (Co2O3).Dub los yog greyish dub hmoov.Qhov pom tseeb qhov ceev yog 0.5-1.5g / cm3, thiab kais ceev yog 2.0-3.0g / cm3.Cobalt Tetroxide tuaj yeem maj mam yaj hauv kub sulfuric acid, tab sis nws yog insoluble hauv dej, nitric acid thiab hydrochloric acid nyob rau hauv chav tsev kub.Thaum rhuab saum 1200 ℃, nws yuav decompose rau hauv cobaltous oxide.Thaum nws tau kub siab rau 900 ℃ hauv cov nplaim hluav taws xob hydrogen, nws txo qis rau hlau cobalt.
