Yttrium hydride is a chemical with antiferromagnetic properties. The bihydride has a calcium fluoride structure and the trihydride has a cubic structure. YH2 is a metallic conductor and conducts electricity better than rare earth metals. Yttrium hydride has important applications in the field of solar cells, which can improve light absorption capacity, enhance photoelectric conversion efficiency, and maintain stability at high temperatures. In addition, yttrium hydride is also used as a preparation material for matrix fuel elements based on fuel particles, which has advantages of high efficiency and saving design space, especially for small modular nuclear reactors or micro-reactors.
