Praseodymium-Zircon Yellow Ceramic Pigment
CAS Number: 68609-53-0
Praseodymium-doped zircon yellow (Pr-ZrSiO4) is a high-performance, environmentally-friendly yellow ceramic pigment used in glazes, ceramic inks, and body stains. The Pr4+ ion substituting into the ZrSiO4 crystal lattice provides intense lemon-yellow color with outstanding thermal stability above 1300 °C and excellent resistance to acids, alkalis, and solvents.
