摘要：
Low scatter water clear zinc sulfide with reduced metal contamination is prepared by coating a chuck which holds zinc sulfide and machining the zinc sulfide with uncoated particles. An inert foil is cleaned with an acid cleaning method and also cleaning the zinc sulfide. The zinc sulfide is wrapped in the inert foil and then treated by a HIP process to provide a low scatter water-clear zinc sulfide. The low scatter water-clear zinc sulfide may be used in articles such as windows and domes.
