How does the purity of black iron oxide pigment affect its UV stability and color consistency?
The Chemical Relationship Between Purity and UV Stability Resistance to Photo-Oxidation: High-purity black iron oxide pigment is inherently UV-stable due to its inorganic crystalline structure. Unlike organic dyes, it does not break down under solar radiation. However, high purity (measured by $Fe_3O_4$ content) ensures the absence of soluble salts that can cause efflorescence, which often mimics...
