EC number: 269-075-7 | CAS number: 68187-15-5 An inorganic pigment that is the reaction product of high temperature calcination in which praseodymium (III) oxide, praseodymium (IV) oxide, silicon oxide, and zirconium (IV) oxide in varying amounts are homogeneously and ionically interdiffused to form a crystalline matrix of zircon. Its composition may include any one or a combination of the modifiers alkali or alkaline earth halides.
