Zirconium Hydride ZrH2 Powder
Zirconium Hydride (ZrH₂) powder is a high-purity, dark grey to black material widely used in nuclear technology, powder metallurgy, and hydrogen storage applications. With a typical hydrogen content of 2.2 wt%, ZrH₂ serves as an effective hydrogen source and reducing agent in high-temperature processes. It is available in various particle sizes, including -60 mesh and 400 mesh, making it suitable for use in pyrotechnics, ignition systems, and advanced alloy production. This zirconium-based powder is valued for its stability, reactivity, and versatility in high-performance industrial and research applications.

Mechanisms of Hydride Nucleation, Growth, Reorientation, and Embrittlement in Zirconium: A Review
Abstract: Hydrogen is easy to gather and precipitates as hydride due to the low solid solubility of hydrogen in Zr . The limit solid solubility of hydrogen in Zr has two categories: terminal solid solubility until the end of hydride dissolution (TSSD) during heating and terminal solid solubility at the start of hydride precipitation (TSSP) during cooling.
