Titanium dioxide (TiO 2) has a high refractive index and, in powder form, is one of the whitest substances on earth. Titanium dioxide pigment is prized for its chemical stability, brightness, non-toxicity and ultraviolet resistance, while titanium metal is known for its extremely high strength to weight ratio and fatigue and oxidization resistance.
