CaMo5O8
CaMo5O8 is a metastable, semiconducting ternary oxide containing calcium and molybdenum.
About CaMo5O8
CaMo5O8 is a complex ternary oxide featuring calcium, molybdenum, and oxygen. As a semiconducting material, it represents a specialized composition within the broader landscape of molybdenum-based oxides, offering unique electronic properties that distinguish it from simpler binary systems. Its structural arrangement is a subject of interest for researchers investigating the interplay between transition metal oxidation states and oxygen coordination environments. Due to its position above the thermodynamic hull, CaMo5O8 is considered a metastable compound. This classification suggests that while it may be synthesized under specific experimental conditions, it exists in a state of higher energy relative to its constituent elements or more stable phase mixtures. Understanding such metastable oxides is vital for advancing synthesis techniques and exploring unconventional material phases.
Key Properties
Cross-validated computational properties for CaMo5O8, aggregated across 3 databases.
