Zirconium Powder Characterization and Process Improvement for Thermal Batteries
Abstract
The inhouse program has resulted in a survey and characterization of existing production raw materials and product Zr metal powder as a heat source in the AF Maverick thermal battery. The variables most likely causing inconsistency and ignition sensitivity of zirconium metal powders are identified. The criteria for design and safety requirements for a laboratory scale zirconium-reduction-leach facility were established. The reduction and leach-wash cycle parameters were optimized to produce consistent quality fine particle 1-2-micrometer zirconium powder. The reduction scale up (400 grams per batch) was achieved in order to produce sufficient quantities of Zr metal powder for performance tests and to evaluate variables. The technology was transferred to the industry for production of 50 pounds/batch Zr metal was accomplished.
