Abstract
This is a method for reducing the chlorides of zirconium, hafnium, or titanium. It utilizes a solidified magnesium (or sodium) chloride matrix in which chunks of the product metal are contained as a seal on the bottom of the reduction vessel. A withdrawal mechanism is used in conjunction with a cooling means (e.g. water jacket) to slowly withdraw the product metal chunks in the salt matrix. This invention makes possible the operation of the reduction process as a continuous process.
