Be4La4O10
Be4La4O10 is a metastable, wide-band-gap insulating oxide containing beryllium and lanthanum.
About Be4La4O10
Be4La4O10 is a complex oxide composed of beryllium, lanthanum, and oxygen. As a wide-band-gap insulator, it exhibits electronic properties characteristic of highly stable dielectric materials, despite its own metastable nature.
Because it exists in a metastable state, this compound represents a unique structural configuration within the beryllium-lanthanum-oxygen system. Its study provides valuable insights into the synthesis and stability of multi-component oxides that do not readily form under standard equilibrium conditions.
Key Properties
