Abstract

A porous sintered zinc body such as a battery anode is made by compacting a powder mixture of oxide coated zinc and ammonium halide and sintering the compact under reduced pressure below the melting point of zinc to effect sublimation of the halide. The porosity is determined by the amount of ammonium halide in the mixture and porosities over 50% are obtained. The reactive sintering is carried out at 1-5 mms. Hg pressure and is preferably effected in two stages, the first stage at a temperature from 200 DEG C. below the sintering temperature to the sintering temperature and finally at the sintering temperature. The chloride, bromide and iodide are the preferred halides. If the fluoride is used complete sublimation does not occur and the remaining fluoride is dissolved out by treating with water.
