What is Chromium trioxide? Chromium trioxide, an inorganic compound with the chemical formula of Cr2O3, is a green crystalline powder, insoluble in water, acid, and alkali solution but soluble in hot alkali bromate solution. It is mainly used for coloring ceramics and enamels and can also be used as an analytical reagent and catalyst. Chromium dioxide (CrO₂) is a brown-black magnetic powder. The relative density is 4.89. It is metastable in the air with a melting point of 350℃. It is decomposed into chromium trioxide and oxygen at 250 ~ 500℃.
MoreaboutChromium trioxide Chemical formula: Cr2O3 Molecular weight: 151.99 CAS：1308-38-9 Melting point: 1435℃ Boiling point: 4000℃ Water solubility: insoluble Density: 5.21 g/cm³ chemical property of Chromium trioxide powder 1. Cr2O3 is amphoteric and can react with acid and alkali; Cr2O3+ 3H2SO4= Cr2(SO4)3+3H2O Cr2O3+ 2NaOH = 2NaCrO2 +H2O 2. Cr2O3 reacts with potassium pyrosulfate at high temperatures: Cr2O3+ 3K2S2O7= 3K2SO4+ Cr2(SO4)3 Uses of Chromium trioxide powder Mainly used for coloring ceramics and enamels and can also be used as analytical reagents and catalysts. Melt-blown grade chrome oxidecan be used as a melt-blown coating, which can be directly sprayed onto metal, ceramic, and other surfaces with the help of high-temperature plasma gas, giving the latter extremely high wear resistance, corrosion resistance, and high temperature resistance; According to needs, chrome oxide green and aluminum oxide or zirconium oxide can be fused together to obtain a refractory material with excellent performance.
