Used in TiO2 coating and in the manufacture of other zirconium chemicals.
Zirconium Oxychloride (ZOC) is used as a source of zirconium to coat TiO2 particles. This enables the surface of the particle to reflect rather than absorb UV light which reduces the yellowing effect of sunlight.
Zirconium Oxychloride (ZOC) is a white crystalline powder with a slight hydrochloric acid odour.
