Structure Properties of LiAl (WO4)2 Solid Solution

Tungstate crystals with the general formula AB (WO₄)₂, where A=Li is the alkaline element; the B=Al is trivalent element have attracted a great attention,for their great optical properties and high performance for many applications, such as optical fibers [1], scintillator materials [2],humidity sensors [3], catalysis [4], phosphor’s and laser’s light,[5]. For this study we analyzed by X-ray diffraction the crystalline structures of our compounds. The use of Xpert HighScore Plus identification. Due to the large difference in ionic radius between Li and Al, the formation of the LiAl (WO₄)₂ phase is incomplete, the goal of this work is to see what is the limit of this phase to see the majority of the LiAl(WO₄)₂ phase, regarding temperature point of view, using the solid state reaction method.
