Calcium-hydride production technology for Zial (Zr-16Al) alloy is developed. In contrast to powder obtained by the grinding of cast alloy, powder produced by calcium-hydride technology is more disperse, with a highly developed particle surface. A method is developed for determining the sorptional capacity of Zial alloy in hydrogen. It is found that Zial powder produced by calcium-hydride technology matches powder obtained from cast alloy in terms of hydrogen sorption and is preferable in terms of carbon-monoxide sorption. X-ray phase analysis shows that gas absorbers made from Zr-16 Al powder produced by the calcium-hydride technology consist mainly of intermetallics Zr(3)Al(2), Zr(5)Al(3), and Zr(4)Al(3). This composition is optimal when using Zial alloy as a getter.
