X-ray diffraction analysis of LiCu<inf>2</inf>O<inf>2</inf> crystals with additives of silver atoms
Silver-containing LiCu<inf>2</inf>O<inf>2</inf> crystals up to 4 × 8 × 8 mm in size were grown by the crystallization of 80(1-x)CuO · 20<inf>x</inf>AgNO<inf>3</inf> · 20Li<inf>2</inf>CO<inf>3</inf> (0 ≤ х ≤ 0.5) mixture melt. According to the X-ray spectral and Rietveld X-ray diffraction data, the maximum amount of silver incorporated in the LiCu<inf>2</inf>O<inf>2</inf> structure is about 4 at % relative to the copper content. It was established that silver atoms occupy statistically crystallographic positions of lithium atoms. The incorporation of silver atoms is accompanied by a noticeable increase in parameter с of the LiCu<inf>2</inf>O<inf>2</inf> rhombic unit cell, a slight increase in parameter а, and a slight decrease in parameter b. © 2015, Pleiades Publishing, Inc.
