Did you know that star sapphires and rubies get their star from naturally occuring titanium dioxide?
Bulk chemicals are supplied for industrial, jewelry and laboratory uses.
Titanium dioxide is inexpensive, nontoxic, and widely used as a white pigment in a multitude of applications, domestic, industrial and artistic. The powder itself is chemically inert. Titanium dioxide pigment is extremely opaque and surface. Its extraordinary opacity allows it to impart a pure white color brown or grey substrates. Titanium oxide pigment accounts for the largest use of the element. Because it is a potent reflector of infrared, it is extensively used in solar observatories where heat is a problem.
Compounds made with titanum dioxide are called "titanates" and include barium titanate, which can be used as a transducer on account of its piezoelectric properties.
Drill bits and other cutting tools are often coated with titanium nitride. Titanium nitride can be used to make decorative finishes in gold tones, and as a barrier metal in semiconductions Titanium nitride is often used to coat cutting tools, such as drill bits. Titanium carbide is a good choice for high-temperature cutting tools.
Fabrics can be waterproofed with esters of titanium. Esters of titanium are formed with alcohols react with titanium tetrachloride.
Unlike the white titanium dioxide, titanium tetrachloride, TiCl4, is colorless. It is mainly used as an intermediate in the manufacture of titanium oxide for paint, and in organic chemistry as a Lewis acid. Titanium isopropoxide is a key element of the Sharpless epoxidation. Another important chemical is titanocene dichloride, a choice catalyst for carbon-carbon bond formation.
