Titanium dioxide, also known as titanium(IV) oxide or titania, is a naturally occurring oxide of titanium with the chemical formula TiO2. It is a white, crystalline solid that is insoluble in water and has a high melting point.
Titanium dioxide is one of the whitest materials on earth, reflecting more bright light than almost any other material. Because of its brightness and very high refractive index, it is used in products like paints, varnishes, paper and plastics to give them a bright white color. It is also used in sunscreens, as it is capable of absorbing ultraviolet light.
Titanium dioxide is also used in food production, often as a colorant to make foods appear white or opaque. It can be found in a range of food products including baked goods, candy, and chewing gum. However, the use of titanium dioxide in food products has been a point of some controversy due to potential health concerns.
From an environmental perspective, titanium dioxide has photocatalytic properties, meaning it can absorb light and convert it into chemical energy. This property has been exploited to create self-cleaning surfaces and can also be used to break down environmental pollutants.
In the industrial process, titanium dioxide is mainly sourced from ilmenite ore and is produced by the sulfate process or the chloride process. It is a common material used in various industries worldwide with an estimated annual production of four million tons.
Despite its numerous benefits and uses, exposure to titanium dioxide has been linked to a number of health risks, especially in nanoparticle form. It can cause respiratory problems when inhaled and may potentially be a carcinogen, although more research is needed in this area.
