Y2Bi2O7 is a metastable semiconducting oxide containing yttrium and bismuth that is primarily used in materials science research.
About Y2Bi2O7
Y2Bi2O7 is a complex oxide composed of yttrium, bismuth, and oxygen. As a semiconducting material, it occupies a unique position in solid-state chemistry, offering interesting electronic properties that are governed by its specific atomic arrangement. Although it is classified as a metastable phase, its existence in multiple reported structures highlights its significance in experimental and theoretical investigations.
This compound is primarily of interest to researchers studying the behavior of bismuth-based oxides under varying synthesis conditions. Its metastability suggests that its formation is highly sensitive to processing parameters, making it a valuable subject for understanding phase stability and structural transitions in oxide systems.
Key Properties
