TiO2
Titanium dioxide, occurring in a number of minerals including ilmenite, rutile and leucoxene. The main commercial application of TiO2 is as a whitening pigment.

Titanium
Titanium is mainly used to produce titanium dioxide pigment which is non-toxic, inert and imparts a brilliance and opacity. It is widely used in paints, plastics and paper. It is also used to produce titanium metal which has a high strength to weight ratio, is non-reactive and resistant to oxidation. It is used increasingly in aircraft and space craft. Because it is non-reactive, it is used extensively in surgery.

Z

Zircon
Zircon is a form of zirconium which because of heat and corrosion resistance properties, is used in chemical processing equipment, sanitary ware, refractories and electronic appliances and also in jewellery as zirconia.
