Zirconium(II) Hydride Powder / ZrH2 Powder (ZrH2, 1-5um, 99%)

Zirconium(II) Hydride Powder

Introduction

Zirconium(II) hydride (ZrH₂) is an inorganic compound that forms when zirconium metal reacts with hydrogen. It exists as a powder or in bulk form and has distinct properties that make it useful in a variety of industrial, nuclear, and technological applications. The zirconium in ZrH₂ has a +2 oxidation state, and the compound is generally synthesized by reacting zirconium metal with hydrogen gas at elevated temperatures and pressures. This hydride is a metal hydride with excellent thermal and mechanical properties, especially when used in high-temperature and high-energy environments.

Zirconium hydride is notable for its ability to absorb and release hydrogen, making it useful in hydrogen storage and fuel cell applications. Additionally, its unique properties, such as high thermal conductivity, neutron absorption capability, and corrosion resistance, contribute to its versatility in different technological fields.
