Applications of 10034-82-9
| Industry | Application | Process |
|---|---|---|
| Metalworking | Metal surface treatment and passivation | Sodium chromate solution is sprayed or immersed onto steel surfaces to form a corrosion-resistant passive film. |
| Dyes & Pigments | Production of inorganic pigments such as chrome yellow and chrome orange | Reacted with lead salts (e.g., lead nitrate) to precipitate lead chromate, followed by washing and drying to yield pigment. |
| Wood Preservation | Wood preservative | A mixture of sodium chromate, sodium dichromate, and copper sulfate is pressure-impregnated into wood to inhibit fungal growth and insect infestation. |
| Leather Industry | Assisting agent in chrome tanning | Acts as an oxidizing agent in chrome tanning, adjusts pH, and promotes stable binding of chromium complexes to collagen fibers. |
| Inorganic Synthesis | Production of other chromium compounds | Reacted with acids to produce sodium dichromate, or used as a chromium source for synthesizing chromates and chromic esters. |
| Petrochemicals | Drilling fluid additive | Added as a corrosion inhibitor to drilling fluids to suppress corrosion of metal equipment in sulfide-containing environments. |
| Glass & Ceramics | Colorant | Added during glass melting or glaze firing to produce yellow-to-green chromate-based coloration. |
