"The 'tungsten bronzes are a series of anionic substitutional solid solutions of alkali or alkaline earth metal metatungstates and tungstic oxide. They are neither alloys or intermetallic compounds, the term "tungsten bronzes" was adopted because of their remarkable metallic properties -- e.g., high electrical conductivity, metallic luster on the crystal, and high specific gravity. Also owing to their intense and vivid colors and chemical inactivity it was possible to use them in the paint industry as a substitute for the so-called "bronze powders", the latter term is applied to the finely divided metal powders, such as aluminum, copper, brass, and bronze powders. The paint made of these tungsten bronzes with some binding materials are used to protect metal surfaces and for ornamental purpose.

The properties and structure of some of those tungsten bronzes are still unknown; in the last two decades, no published investigation about lithium tungsten bronzes has been made.

The present work is intended to find out the structure and some other properties of the lithium tungsten bronzes, the solubility of tungstic oxide in the bronzes, and the lattice changes with increasing amount of WO3 in such a solid solution series. These points have not been reported by previous workers. Some chemical and metallurgical processes are involved in this investigation; theories and technique of x-ray diffraction are applied, the samples are identified, and the structure and lattice constants of lithium tungsten bronzes are found from x-ray powder photographs applying 'Straumanis' technique'"--Introduction, pages 1-2.
