Abstract
A method for casting a reactive material PVD target, as well as targets thus obtained and a mold for casting. The method includes providing a mold defining an opening, placing a reactive material ingot in to a reservoir (140) proximate the mold, forming a vacuum and melting the reactive material in the reservoir, heating the mold to above a casting temperature and forming a vacuum therein, introducing molten reactive material from the reservoir into the opening and cooling the mold to form the PVD target.
