A getter-filter composite membrane element, comprising a sinterable getter material and a sinterable metal filter material, the composite element defining a matrix of substantially interconnected pores. Membrane elements may be comprised of at least three alternating layers of a first sinterable getter material layer and a second sinterable metal filter material layer, the first getter layer being located between the second filter layers, the second layers acting to hold the getter layer, and to retain the getter particles. Also disclosed is a method of making the getter-filter element. |
