Fe3+-Substituted Sr6YAl(BO3)6 Red Pigments Designed Without Pb, Cd, or Hg: Colour Performance, Chemical Stability, and Elemental Release Screening

Red inorganic pigments traditionally rely on Pb-, Cd-, Hg-, or Cr(VI)-based colourants that carry avoidable hazard and exposure risks. Here, a family of Sr6YAl1−xFex(BO3)6 (0 ≤ x ≤ 1) pigments was prepared by solid-state reaction using Fe3+ as the chromophore and no Pb-, Cd-, Hg-...
