Since ZrO2 is obtained by complex and expensive purification process from
zircon sands, synthesis of a pigment by using zircon or intermediate
in the process of making ZrO2 might have a significant
economical advantage. Several numbers of patents have
claimed that intermediate products in the process of making
ZrO2 from zircon can be used to produce zircon pigments, which
has more regular and intense hue.
