The purpose of this thesis is to give a summary of the work done in studying the equilibrium conditions and rate of reaction of the compound tungsten hexachloride, together with some of its applications to the elimination of spots in coiled filaments. Tungsten hexachloride is a purple colored crystalline compound formed by passing chlorine over red hot tungsten in a tube from which all the air has been washed. It is rather unstable at room temperature in the presence of moist air, forming an oxychloride formula WoCl4 and then decomposing into tungsten oxide into the formula WO3 and the vapor decomposes at still higher temperatures. It volatilizes appreciatively at about 150 degrees C in vacuum and at about 320 degrees C in hydrogen.
