Abstract

This invention provides a method for the production of amorphous metal containing compounds including the steps of providing a soluble crystalline salt of the metal in solid form; and reacting the soluble crystalline salt directly with an alkaline solution, without first dissolving the salt. A filterable and yet relatively very reactive, granular, amorphous-, and more particularly a pseudo-crystalline hydroxide or carbonate is obtained and which has substantially the same physical form as the salt. This provides for the easy separability of the granules from the solution. In addition, the porous nature of the amorphous product allows for the virtual complete removal of soluble by-products from the interior of the particles by efficient washing procedures, as a concentrated solution, which can be utilised for other purposes in an economical fashion.
