Properties

Physical Form
Note
  • 5 In iron oxide black pigments, a chemical transformation (oxidation) is also recorded when determing the loss on ignition.
  • 53 Minor elements may arise from the raw materials used. However, these are firmly bound to the crystal lattice as ions.

Storage & Handling

Storage Conditions
  • Protect against weathering. Store in a dry place and avoid extreme fluctuations in temperature.
  • When storing large quantities of pigments, temperatures above 80 °C must be avoided as an alteration (oxidation) of the pigment may be caused by heat.
  • Special conditions for opened packaging: Close bags after use to prevent the absorption of moisture and contamination.
