sheet for grinding into powder. The deposit may also be in powder form. In present commercial practice, iron is deposited as a brittle sheet which is ground to powder, whereas copper is deposit ed in powder form. The powder is then annealed in a reducing at mosphere to soften the particles and to lower the oxide content of the powder.
