Applications of 7788-99-0
| Industry | Application | Process |
|---|---|---|
| Leather Industry | Leather tanning to improve heat resistance, softness, and shrinkage temperature | Applied in the chrome tanning step following pickling; used synergistically with basic chromium sulfate to control pH and tanning intensity |
| Electroplating Industry | Primary salt component in trivalent chromium plating baths for decorative and functional chromium plating | Formulated into trivalent chromium plating solutions, typically blended with complexing agents (e.g., formates, acetates) and conductive salts; cathode current efficiency approximately 25–30% |
| Dyeing & Printing Industry | Mordant to enhance color fastness and brightness of dyes on fibers | Added prior to or during dyeing; forms insoluble lake pigments with hydroxyl- or amino-containing dyes (e.g., acid dyes, mordant dyes) |
| Catalyst Manufacturing | Precursor for chromium-containing catalysts used in organic synthesis and petroleum cracking | Converted into Cr₂O₃ or composite oxide catalysts—such as Cr-Al₂O₃ dehydrogenation catalysts—via thermal decomposition or co-precipitation |
| Pigments & Ceramics | Raw material for green pigment (chrome green) in ceramic glazes and artists’ pigments | Thermally decomposed at high temperature (800–1200 °C) to yield Cr₂O₃, followed by fusion with other metal oxides to develop color |
