Ca4Mg3H14 is a complex hydride ceramic compound combining calcium, magnesium, and hydrogen—materials of interest in energy storage and advanced ceramics research. This composition represents an experimental material from the metal hydride family, which is primarily investigated for hydrogen storage applications and as a potential solid-state electrolyte or thermal management material in emerging energy technologies. While not yet established in mainstream industrial production, hydride ceramics of this type are notable for their low density and potential to bridge conventional ceramics with hydrogen-rich functionality, making them candidates for next-generation applications in fuel cell systems, thermal batteries, or hydrogen economy infrastructure.
