100g Potassium Dichromate Powder 99% Lab Grade
Premium Potassium Dichromate (K₂Cr₂O₇) – Vivid Orange-Red Crystals, ACS/Reagent Grade
Transform your workspace with the unmistakable brilliance of potassium dichromate — nature's most striking orange-red crystalline solid. These dense, gem-like crystals glow with an intense, almost fiery red-orange hue that deepens to rich crimson in larger formations, making them a favorite among chemists, photographers, woodworkers, and educators who appreciate both beauty and precision.

- Traditional photography & holography — essential sensitizer in gum bichromate, carbon printing, and early cyanotype/alternative processes
- High purity — suitable for laboratory, analytical, and small-scale artisan applications

Important Safety NoticePotassium dichromate is a powerful oxidizer and contains hexavalent chromium. It is toxic if swallowed, inhaled, or absorbed through skin, a mutagen, and severe irritant/corrosive to eyes and skin. Use only with appropriate engineering controls, full PPE (nitrile gloves, respirator, face shield, lab coat), and in a properly ventilated fume hood. Dispose of according to local hazardous waste regulations — never pour down the drain.
Perfect for:
