titaniinioksidista

Titaniinioksidi is the Finnish term for titanium dioxide, a naturally occurring oxide of titanium. Its chemical formula is TiO2. It is a white, powdery solid that is highly insoluble in water. Titaniinioksidi is known for its exceptional whiteness, brightness, and opacity. It is also a semiconductor material with a high refractive index.

The primary use of titaniinioksidi is as a pigment. It is the most widely used white pigment in the world, found in paints, coatings, plastics, paper, inks, and even cosmetics and food products. Its ability to scatter light makes it an excellent opacifier, meaning it can hide underlying surfaces. In the food industry, it is used as a food coloring additive, often labeled as E171 in Europe.

Beyond its pigmentary applications, titaniinioksidi has significant industrial uses. Its photocatalytic properties are exploited in self-cleaning surfaces, air and water purification systems, and in the production of hydrogen. It is also used in sunscreens due to its ability to block ultraviolet (UV) radiation. The production of titaniinioksidi involves complex chemical processes, with the two main methods being the sulfate process and the chloride process. Different crystalline forms of titaniinioksidi, such as rutile and anatase, exhibit varying properties and are used in specific applications.
