Titanium dioxide treatment

 

Titanium dioxide is a bright white, non-toxic, persistent solid (a fine powder) which is mainly used as a pigment in paints and paper. When heated, it turns yellow, and after cooling the white pigment will return. Under the impact of light, the substance becomes a semiconductor, which is why it is used to transform solar energy into electrical energy in solar cells.
The advantages of titanium dioxide concrete elements are their better resistance to weather conditions, self-cleaning of concrete surfaces and its brighter and lighter appearance. It has also been found that concrete walls treated with titanium dioxide clean the environment by binding nitrogen compounds from the air when exposed to UV radiation.
