· JVASP-52829· K2ZnH4

K2ZnH4 is a metal hydride ceramic compound containing potassium, zinc, and hydrogen, representing an emerging class of materials in solid-state hydrogen storage and advanced ceramics research. This compound belongs to the family of complex metal hydrides being investigated for hydrogen economy applications, where the ability to store and release hydrogen under moderate conditions makes it of interest for clean energy systems. K2ZnH4 and related zinc hydrides are primarily explored in research contexts rather than established commercial production, with potential applications in hydrogen storage systems and solid electrolyte materials where chemical stability and hydrogen capacity are critical performance drivers.
