Molecular formula: CrO3
Molecular weight: 99.99
EINECS No.:215-607-8
Chemical Properties:Dark red rhombohedral crystal or purple-red flake.
Uses:Used in electroplating, making high purity chromium metal, dyestuff, synthetic rubber and oil refining, etc.
Use: This product is the main raw material for chromium plating. In the production of chromium plating, the content of chromic anhydride varies greatly, between 50 and 500 g/L, the main control of the appropriate temperature and current density, can be obtained in the smooth plated parts on the bright coating, its solution can also be used for zinc plating passivation film, so that its protective properties.
Uses:It is mainly used in electroplating industry as raw material for chromium plating of bicycles, sewing machines, watches, meters, torches, daily-use hardware, etc. It is also used for making high-purity chromium metal. It is the raw material for the manufacture of chromium oxide green and zinc chromium yellow; it is also the raw material for the production of low-temperature transformation catalyst, high-temperature transformation catalyst and high-pressure methanol synthesis catalyst. It is used as mordant when dyeing wool fabrics and as oxidising agent in the printing and dyeing industry. In addition, it is also used for wood preservation.
Uses: Its solution is used for chromium plating.
Uses:Used as an analytical reagent and strong oxidising agent, also used in the manufacture of chromates.
Use: Strong oxidising agent. Determination of carbon and phosphorus. Purification of oil and ethylene. Manufacture of chromium salts.
Uses: Oxidising agent, glass colouring, raw material for making oxidising catalysts.
What is automotive urea for cars? What is the function of automotive urea for cars?Automotive urea is a colourless transparent liquid, its main components are urea and distilled water. The chemical formula of urea is CO(NH2)2, a nitrogen-containing organic compounds, with strong reducing properties.- What is sulfamic acid and its uses?Sulfamic acid is a white crystalline solid, stable and non-hygroscopic. It is soluble in water and formamide and slightly soluble in methanol, ether, acetone and concentrated sulphuric acid. It is classified as a strong inorganic acid and is produced commercially from urea and fuming sulphuric acid.

- Role of sodium k12 dodecyl sulphateWhite or light yellow powder or liquid, slightly with grease odor. Easily soluble in water, can reduce the surface tension of aqueous solution and emulsify grease. Insensitive to alkali and hard water, good compatibility with anion and nonion. This product is combustible, irritating and sensitizing. It can be ignited by open fire and high heat. Heat decomposition releases toxic gas.
