ceramic

· JVASP-37663· PrH3

PrH3 is an intermetallic hydride ceramic compound based on praseodymium, belonging to the rare-earth hydride family of materials. This material is primarily of research and exploratory interest rather than established commercial production, studied for its potential in hydrogen storage, neutron absorption, and specialized high-temperature ceramic applications where rare-earth compounds offer unique electronic or thermal properties.
