Zinc Vapor Trapping Using Copper-Based Materials
As part of the development of a long range solution for zinc vapor capture, a series of experiments utilizing commercially available copper and bronze screen and bronze sheet materials were conducted. The testing used a high-vacuum system in which zinc was vaporized and condensed on the zinc getter material at various temperatures. A fixed zinc vaporization temperature was used and the zinc getter material, and consequently the condensation temperature, was varied. The testing revealed that zinc vapor was captured over a wider range of temperatures on bronze materials than on the copper screens.
