Titanium Tetrachloride (TiCl4) is the precursor in the manufacture of Titanium Dioxide (TiO2). TiO2 is a bright white pigment used in the formulation of most colors in products ranging from paints to toothpaste. Titanium Tetrachloride is a highly volatile, toxic, slurry that requires special cantilever or sealless pump designs to handle entrained abrasive solids and prevent fugitive emissions.
