| Summary |
"The tungsten bronzes are a series of anionic substitutional solid solutions of alkali metal metatungstates and tungstic oxide. They are neither alloys nor intermetallic compounds, the term tungsten bronzes was adopted because of their remarkable metallic properties, e.g. luster, specific gravity and especially high electrical conductivity, which resembles to that of graphite. Due to its chemical inactivity and beautiful shades of color, it is used as a coating, especially in the plastic industry and for other ornamental products. The properties and the structure of these bronzes have not been investigated entirely satisfactory; within the last twenty years, only a few published information worth mentioning has been made. The present work is intended to find out some of these still unknown properties of the bronzes...For this purpose, the X-ray method of investigation was widely applied. It turned out that only with this method, satisfactory results could be made"--Introduction, leaf 1. |
