Potassium Dichromate

SOLUBLE SOURCE OF CHROME OXIDE

Chemistry K2O 32.000 Cr2O3 51.700

Volatiles LOI 16.300

Hazards

• Potassium Dichromate

Miscellaneous

• Family: Colorant
• Region: None
• Mined At: Unspecified
• Raw Mineral: No
• Generic: No

Notes

A soluble crystalline bright orange powder. It is used to introduce Chromium oxide into low temperature glazes to achieve colors such as red. The chromium is more effectively dispersed because it is combined with potassium.

Decomposes: 500C

Data

• Melting Point (MP): 400C M
• Specific Gravity: 2.69
• Specific Gravity: 2.69
• Melting Point (MP): 400C M
