General Description

Hafnium hydride is a chemical compound composed of hafnium and hydrogen atoms with the formula HfH?. It is a metallic hydride that is commonly used as a neutron absorber in nuclear reactors due to its high thermal neutron capture cross-section. Hafnium hydride is also used in the aerospace industry as a component in high-temperature thermal protection systems and in superalloys for turbine blades. It is a stable and non-toxic material with a high melting point, making it suitable for various industrial applications requiring strong and heat-resistant materials. Hafnium hydride is typically produced by reacting hafnium metal with hydrogen gas at elevated temperatures.
