  • Powdered metal filter composition and processes for producing the same
    Patent number: 4287068
    Abstract: A powdered metal filter composition and processes for producing the same by water atomization in which the composition exhibits an apparent density, compressibility and particle shape as a function of the composition chemistry and in particular the silicon, carbon and manganese content as well as the angle of intersection of the atomizing water jets; the composition providing an optimization of filtration efficiency, pressure drop across the filter pack, resistance to pressure deformation of the composition particles and the useful life of both the filter pack and the composition and the process producing such a composition with well-known apparatus and optimum yields of useful, particle-size fractions.
    Type: Grant
