Na2TiF6

Na2TiF6, also known as sodium hexafluorotitanate, is a chemical compound composed of sodium (Na), titanium (Ti), and fluorine (F). It is a white crystalline solid that is soluble in water. The compound is notable for its use in the production of titanium dioxide (TiO2), a white pigment used in paints, coatings, and plastics. Na2TiF6 is typically synthesized through the reaction of titanium tetrachloride (TiCl4) with sodium fluoride (NaF) in a hydrofluoric acid (HF) medium. The reaction can be represented as follows: TiCl4 + 4 NaF → Na2TiF6 + 4 HCl. The compound is also used in the production of other titanium compounds and as a precursor in the synthesis of titanium-based materials. Na2TiF6 is relatively stable under normal conditions but can decompose upon heating, releasing hydrogen fluoride (HF) gas. It is important to handle Na2TiF6 with care due to the toxic nature of HF. The compound has a monoclinic crystal structure and is often used in research for its unique properties and potential applications in materials science.
