SINTERED FILTER

PURPOSE:To produce the sintered filter exhibiting a constant pressure drop by sintering a granular material obtained by coating a core of a material having a high m.p. with a material having a lower m.p. than the core at a temp. higher than the m.p. of the surface material and lower than the m.p. of...

Beschreibung
Zusammenfassung:	PURPOSE:To produce the sintered filter exhibiting a constant pressure drop by sintering a granular material obtained by coating a core of a material having a high m.p. with a material having a lower m.p. than the core at a temp. higher than the m.p. of the surface material and lower than the m.p. of the core. CONSTITUTION:Granular resin, glass or metal are sintered to form a sintered filter. In this case, the high-m.p. material 1b is used as the core, and its surface is coated with the material la having a lower m.p. than the core material 1b to obtain the granular resin, glass or metal. The two-layer granular material is sintered at a temp. higher than the m.p. of the surface material la and lower than the m.p. of the core material lb. As a result, a filter exhibiting a constant pressure drop is easily produced even if the set width of the sintering temps. of the sintered filter is increased.
