Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4] It is a white solid that is insoluble in water, although mineral forms can appear ...
Titanium tetrachloride is also used to make titanium dioxide, e.g., for use in white paint. [52] It is widely used in organic chemistry as a Lewis acid, for example in the Mukaiyama aldol condensation. [53] In the van Arkel–de Boer process, titanium tetraiodide (TiI 4) is generated in the production of high purity titanium metal. [54]
Titanium tetrachloride is also used to make titanium dioxide, e.g., for use in white paint. [19] It is widely used in organic chemistry as a Lewis acid, for example in the Mukaiyama aldol condensation. [20] In the van Arkel–de Boer process, titanium tetraiodide (TiI 4) is generated in the production of high purity titanium metal. [21]
Titanium dioxide nanoparticles, also called ultrafine titanium dioxide or nanocrystalline titanium dioxide or microcrystalline titanium dioxide, are particles of titanium dioxide (TiO 2) with diameters less than 100 nm. Ultrafine TiO 2 is used in sunscreens due to its ability to block ultraviolet radiation while remaining transparent on the ...
The chloride process is used to separate titanium from its ores. The goal of the process is to win high purity titanium dioxide from ores such as ilmenite (FeTiO 3) and rutile (TiO 2). The strategy exploits the volatility of TiCl 4, which is readily purified and converted to the dioxide.
In fact, the titanium dioxide mostly got its cancer-causing reputation because it’s in the form of tiny particles—not because of a chemical response, says Hans Plugge, SM, MSc, senior ...
Titanium dioxide (TiO2) is a bright white substance first named and created in a laboratory in the mid-19th century. It was initially used as a pigment in the ceramic arts for yellow glazes later in the century, and by the 1890s artists started to use white mixtures containing the compound.
The California Food Safety Act was colloquially referred to as the “Skittles ban” before its passage because an earlier version of the bill also targeted titanium dioxide, which is used to ...
