A method of obtaining filter materials from metal powders intended to significantly improve the uniformity of properties along their working surface has been described. The method is easy to perform and is based on granulating the initial powders by the porogen through transferring it into an aqueous solution. It eliminates the segregation of porogen in the bulk of the charge during the implementation of technological operations and enables the automation of the pressing process.
