Abstract
The invention relates to a filter element having inherent stability and being porous to permit flow therethrough, comprising a filter body which forms a porous sintered structure and is constructed with filter body particles which are at least in part polysulfide particles. In addition, the invention relates to a method of manufacturing such a filter element.
Claims27
A filter element (30) being porous to permit flow therethrough, comprising a filter body (20) which forms a porous sintered structure and is constructed with filter body particles (10, 14) which are at least in part polysulfide particles (10), wherein:
- the polysulfide particles (10) contain a tempered polysulfide;
- and
- the tempering is carried out at a temperature of 255° C. to 275° C. over a period of time from 7 to 24 hours prior to sintering.
A method of manufacturing a filter element (30) having inherent stability and being porous to permit flow therethrough, said method comprising steps of:
- Providing filter body particles comprising polysulfide particles (10), at least part of said polysulfide particles tempered at a temperature of 255° C. to 275° C. over a period of time from 7 to 24 hours, and sintering the filter body particles to form a porous sintered filter body (20) of the filter element (30).
