C4Ca4O8
C4Ca4O8 is a metastable, insulating compound containing calcium, carbon, and oxygen that is primarily studied for its complex structural characteristics.
About C4Ca4O8
C4Ca4O8 is a complex inorganic compound composed of calcium, carbon, and oxygen. As a wide-gap insulating material, it exhibits distinct electronic properties that differentiate it from conductive metallic or semiconducting phases, making it a subject of interest for fundamental structural studies. Its metastable nature suggests a unique energy landscape, often requiring specific synthetic pathways to achieve stability. Researchers investigate such compounds to understand the structural diversity possible within calcium-based carbonaceous systems. Given its status as a metastable phase, it serves as a valuable case study for exploring phase transitions and the limits of structural configuration in complex oxide-carbon frameworks.
Key Properties
