High-Pressure Synthesis of Non-Stoichiometric Li(x)WO(3) (0.5 ≤ x ≤ 1.0) with LiNbO(3) Structure

Compounds with the LiNbO(3)-type structure are important for a variety of applications, such as piezoelectric sensors, while recent attention has been paid to magnetic and electronic properties. However, all the materials reported are stoichiometric. This work reports on the high-pressure synthesis...

description Compounds with the LiNbO(3)-type structure are important for a variety of applications, such as piezoelectric sensors, while recent attention has been paid to magnetic and electronic properties. However, all the materials reported are stoichiometric. This work reports on the high-pressure synthesis of lithium tungsten bronze Li(x)WO(3) with the LiNbO(3)-type structure, with a substantial non-stoichiometry (0.5 ≤ x ≤ 1). Li(0.8)WO(3) exhibit a metallic conductivity. This phase is related to an ambient-pressure perovskite phase (0 ≤ x ≤ 0.5) by the octahedral tilting switching between a(−)a(−)a(−) and a(+)a(+)a(+).
