Abstract

Improvements introduced in the object of the main Patent No. 266,660, issued on June 12, 1961, by: "A method of preparing powders for compression and heat treatment" particularly for the manufacture of ferromagnetic materials or a ceramic material, comprising the operations to grind the composition to be reduced to powder, then add an organic binder in a volatile solvent and a lubricating agent and dry the composition beforehand, then press it to the desired shape by preheating the pressed body below the precipitation temperature and not leave virtually no residue of the lubricating agent or binder and then precipitate to form the ceramic body, the lubricating agent being such that it does not evaporate appreciably at the previous drying temperature and is added together with the binder before the previous drying and if the lubricating agent is such that it evaporates appreciably at the Prior drying, the binder is first added, the composition is previously dried and then the lubricating agent is added, thereby avoiding excessive loss of lubricating agent due to prior drying.
