Chemical Description

Leather Tanning

  • Potassium dichromate is used mainly as a precursor to potassium chrome alum in leather tanning.

Cleaning

  • It has been used to make "chromic acid" for cleaning glassware and etching materials, but due to safety concerns with hexavalent chromium, this use is declining.

Construction

  • It's an ingredient in cement that delays setting, improves density and texture, but can cause contact dermatitis.

Photography and Printing

  • Used for hardening organic colloids like gelatin, making them insoluble and forming a relief image after washing away unhardened areas.
  • Employed as photoresists in making metal printing plates.

Film Processing

  • Potassium dichromate, mixed with hydrochloric acid, is used for chromium intensification to strengthen weak negatives in black and white photography.
  • Can produce a positive transparency from a negative film when mixed with sulfuric acid.

Screen-Printing

  • Used in photographic screen-printing, where it hardens a colloid on silk screens in light, creating a mask for printing.
