Detailed Product Description:
Also known as Chromic Oxide, Chromium (II) Oxide is comprised of
bright green, hard crystals. Insoluble in water.
This is reagent grade material with minimum purity of 98%.
Power has 50 micron particle size.
Chromium(III) oxide is one of principal oxides of chromium, widely
used as a precursor to other chromium compounds.
Chromic Oxide adopts the corundum structure, consisting of cubic
close packed oxides with 2/3 of the octahedral holes occupied by
chromium. It is antiferromagnetic up to 307 K. It is an amphoteric
oxide, dissolving in acids to give chromium(III) salts and in molten alkali
to give chromites.
It is manufactured from the mineral chromite, Fe(CrO2)2, which is mined
in southern Africa, Asia, Turkey, and Cuba. The conversion of chromite to
chromia entails air oxidation to Na2Cr2O7, which is subsequently reduced
with carbon or sulfur.
Chromic Oxide is commonly found in paints as a pigment, in abrasives and in
Ceramics. It is also used as a catalyst in APCP (Ammonium Perchlorate
Composite Propellant) solid rocket fuels to enhance ignition.
It is commonly called chrome green or institutional green when used as a
pigment; however it was referred to as viridian when it was first discovered.
Read and understand all precautions in the material safety data sheet
before use of this substance. Toxic by ingestion and inhalation.
