Applications of 304-59-6
| Industry | Application | Process |
|---|---|---|
| Electronics Industry | Raw material for electroplating | Acts as a complexing agent in cyanide-based silver, copper, gold, and zinc electroplating processes to enhance cathodic polarization, yielding fine-grained, uniform deposits with improved adhesion. |
| Chemical Industry | Chemical reagent and analytical standard | Serves as a complexing agent to mask copper ions in Fehling’s and Benedict’s reagents for quantitative analysis of reducing sugars; also functions as a complexing agent in pharmaceutical manufacturing. |
| Pharmaceutical Industry | Pharmaceutical excipient and raw material | Used as a laxative component: its salts remain poorly absorbed in the gastrointestinal tract, generating an osmotic gradient in the intestinal lumen that stimulates peristalsis; also employed in formulating pharmaceutical buffer solutions. |
| Food Industry | Food additive | Registered as food additive E337; primarily used as an acidity regulator, stabilizer, and chelating agent in the production of baking powder, jams, confectionery, and beverages. |
| Construction Materials Industry | Cement retarder | Functions as a retarder in cement or gypsum slurries to slow down the hydration rate and adjust setting time to meet construction requirements. |
| Mirror Manufacturing Industry | Silver mirror reaction aid | Used in conjunction with ammoniacal silver solutions during mirror production and silvering of thermos flask linings to prevent premature silver ion precipitation and ensure uniform, reflective silver coatings. |
| Textile Dyeing and Printing Industry | Mordant | Applied in acidic mordant dyeing of wool and other fibers, in combination with dichromates, to improve dye affinity and colorfastness. |
| Telecommunications Equipment Industry | Piezoelectric crystal manufacturing | Serves as the primary raw material for potassium sodium tartrate (Rochelle salt) crystals, leveraging their pronounced piezoelectric effect in the manufacture of pickups, loudspeakers, and ultrasonic device components. |
