Titaniinioksidi

Titaniinioksidi, also known as titanium dioxide, is a naturally occurring oxide of titanium. It has a chemical formula of TiO2 and is a commercially important compound in various industries. The compound is composed of titanium and oxygen, with a rutile crystal structure.

Titanitiumioksidi is synthesized industrially through the sulfate process or the chloride process. The sulfate process involves the reaction of titanium-bearing ores with sulfuric acid, followed by hydrolysis and precipitation of the dioxide. The chloride process uses titanium tetrachloride as the precursor. The resulting powder can be further purified and compacted into various forms, including rutile structure and anatase structure.

Titaniinioksidi has a wide range of practical applications due to its unique properties. As a pigment, it is used in the manufacture of white paints, plastics, and paper. Titaniinioksidi is also used as a UV-blocking agent in sunscreens due to its ability to absorb ultraviolet light. Additionally, it has applications in the production of coatings for glass and ceramics, textiles, and the pharmaceutical industry. Its photovoltaic and photocatalytic properties also make it suitable for use in water purification systems.

Titaniinioksidi is generally considered to be non-toxic and environmentally stable. However, its use as a pigment has raised concerns regarding environmental pollution, as the compound has been linked to the formation of particulate matter that contributes to smog formation. Regulations and standards have been implemented in many countries to govern the use and emission of titaniinioksidi and other particulate matter.
