Hafnium fluoride powder, also known as HfF4, is a white crystalline solid with the chemical formula HfF4. It is a binary compound composed of hafnium and fluorine.

Hafnium fluoride powder is produced through a reaction between hafnium oxide or hafnium metal and hydrogen fluoride gas, followed by a purification process to remove impurities. The resulting powder is a highly pure material with a range of industrial applications.

Hafnium fluoride powder is used as a source material for the deposition of hafnium fluoride thin films through physical vapor deposition or chemical vapor deposition processes. These films are used as optical coatings, anti-reflection coatings, and as protective coatings for high-temperature applications.

Hafnium fluoride powder is also used as a dopant in the manufacture of optical fibers, as it can increase the refractive index of the glass, thereby improving its performance in telecommunications applications.
