Chromium Oxide, 200 grams #011-1253
Chromium Oxide, 200 grams
Chemical Name:
Chromium (II) Oxide
CAS Number:
Chemical Formula:
Chromic Oxide, Chromia

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.
