Abstract: The invention relates to a method for producing porous metal sintered molded bodies, wherein expandable polymer particles, in which a sinterable metal powder is dispersed, are expanded to form a molded body. The molded body is subjected to a heat treatment, wherein the polymer is expelled and the sinterable metal powder is sintered to form a porous metal sintered molded body. Preferably, styrol polymers are used. The sinterable metal powder is selected, for example, from aluminum, iron, copper, nickel, and titanium.

Abstract: The invention relates to a method for producing hollow bodies having freely displaceable particles enclosed in the hollow body, wherein a) a gel-forming liquid in which the particles are suspended is brought into a cross-linking bath, b) the gel cores that form are isolated, c) the cores are coated with a composition comprising sinterable material and a binder, and d) the coated cores are subjected to a heat treatment wherein the gel and the binder are expunged and the sinterable material is sintered into a closed shell. The gel forming material is, for example, sodium alginate, and the cross-linking bath comprises calcium ions. The particles are selected, for example, from ZrO
2 , AI
2 O
3 , TiO
2 , and SiO
2 or mixtures thereof. The sinterable material is, for example, a metal powder such as carbonyl iron powder.
