- Its solution is used in chromium plating industry, mainly including:
- Mainly used in electroplating industry, to be the raw material for electroplating chromium for bicycles, sewing machines, watches, meters, torches, daily-use hardware, etc. It is also used to make high-purity metal chromium. 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.
- It is used as the catalyst for medium pressure polyethylene production by Phillip's method;
- An important chromium compounds, chromic anhydride is the most important raw material for the electroplating industry, used as the main raw material for chromium electroplating. Most of the chromic anhydride consumption in the electroplating industry. Chromic anhydride is a good oxidising agent, can be used for bleaching, refining, but also can be used as a raw material for dyestuffs, mordant, tanning agents and catalysts for organic synthesis reactions. In addition, it is also used in medicine, ceramics, coloured glass and other industries. 4、Used as analytical reagent, strong oxidant and chromate preparation.
- Used as catalyst for synthesising polyethylene. Also used in chromium plating, mordant and preparation of pure metal chromium.
- In the galvanic passivation in the passivation of zinc plating layer in most of the use of chromic anhydride, which is the main component of the film. In the chemical oxidation of aluminium and alloys, chromic anhydride is the oxidant in solution, and it is an indispensable component for the formation of film layer.
- Used in electroplating industry, pharmaceutical industry, printing industry, tanning and fabric dyeing and so on.
