use
Widely used in chrome plating, wood preservation, medicine, catalysts, pigments, antioxidants, colored glass, textile mordant, producing an oxidizing catalyst raw materials.
package
Inner packed in sealed special barrel, barrel, net weight 25kg (Φ370x330Φx225mm), 50kg (Φ365x435mm), 100kg (Φ430x750mm), 200kg (Φ450x1000mm) or (Φ560x890mm).
Precautions
1, not with combustibles, reducing agents, organic substances coexist.
2, storage and transportation should pay attention to moisture, heat, anti-strike, away from flammable substances.
3, avoid contact with eyes, skin contact.
4, personal protective equipment should be worn self-contained breathing apparatus, acid-resistant rubber gloves, clothing, boots, protective chemical safety glasses.
5. The disclosure should be isolated leak contaminated areas, restricting access to the spill collection, recycling or shipped to the waste disposal sites.
Recommendations
Product main content, low impurities, sulfate is relatively low, regular maintenance, such as a press 50kg / barrel chromic anhydride calculations, the addition of reagents or analytical grade sulfuric acid 30--50ml. (This is the ratio of the amount of chromium was added in an amount of daily maintenance, the actual analysis should also report adjusted according to test cycle)

Water Solubility:H2O: Highly soluble
Storage Conditions:Do not store near combustible materials. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away fr
Vapor Pressure:Very low
Flammability characteristics:CrO3: Noncombustible Solid, but will accelerate the burning of combustible materials.
Odor:Odorless
PH:Dissolves in water to form a weak acid
Experimental Properties:Chromium trioxide, CrO3, contains hexavalent chromium. Its molecular weight is 100.01. It is also known as red oxide of chromium, chromic anhydride, chromic acid anhydride and, erroneously, chromic acid.|Heat of fusion: 37.7 cal/g|Deliquescent|Hexavalent chromium is linked to oxygen and is a powerful oxidizer, but it does not form coordination compounds, and is easily reduced to chromium trioxide. /Hexavalent chromium/|For more Other Experimental Properties (Complete) data for CHROMIC TRIOXIDE (8 total), please visit the HSDB record page.
Air and Water Reactions:Deliquescent. Water soluble, giving acidic solutions.
Reactive Group:Anhydrides
Reactivity Alerts:Strong Oxidizing Agent
Reactivity Profile:CHROMIUM TRIOXIDE is a powerful oxidizing agent. Can react violently upon contact with reducing reagents, including organic matter, leading to ignition or explosion. Dangerously reactive with acetone, alcohols, alkali metals (sodium, potassium), ammonia, arsenic, dimethylformamide, hydrogen sulfide, phosphorus, peroxyformic acid, pyridine, selenium, sulfur, and many other chemicals [Sax, 9th ed., 1996, p. 852]. Noncombustible but can accelerate the burning of combustible materials. Sufficient heat may be generated from the reaction with combustible materials to ignite the mass. Aqueous solutions corrode many metals rapidly. Often mixed with sulfuric acid to make "cleaning solution" for glass. Used cleaning solution in closed bottles may explode due to the build up of gaseous carbon dioxide arising from oxidation of organic impurities [Bryson, W. R., Chem. Brit., 1975, 11, p. 377].
Autoignition Temperature:May ignite organic materials on contact. (USCG, 1999)
Flammable Limits:CrO3: Noncombustible Solid, but will accelerate the burning of combustible materials.
