Application

 

1. It's mainly used for Chromeplate, wood preservation, medicine, catalyzer , printing, oxidant, oxidation acceleration

2. Chromic acid lotion is the laboratory commonly used cleaning fluid, both acid and oxidizing, can remove experimental instrument of the outer            wall of the wall and the dirt and insoluble substance.

3. Usually this lotion by K2Cr2O7 to join in the concentrated sulfuric acid, but hexavalent chromium is harmful to the environment,              strongly acidic environment sometimes also can make the instrument is impaired, at the moment, therefore, the application of chromic acid fluid        has been reduced.

4. Chromic acid is also chrome plating coating of intermediates, is also used in some glaze and color glass production.
 

 5. It is mainly used for Chromium-plating and highly-pure-metal chromium making and used as the raw material for making chromic oxide,mordant      for dyeing woolen fabrics,raw material for making calalyst and oxidizer in organic synthes is in dustry.
