On Laboratory Production of Foam Zinc with Composition Method

The key to production of many types of batteries is the quality of their zinc electrode. Foam zinc alloy is essential to many types of batteries. We propose composition method as a new and better laboratory manufacturing method of zinc foams. The influence of mould preheating temperature and that of molten metal pouring temperature were investigated experimentally. The parameters of pore structures of the new type zinc foams were calculated. Its compression curves were measured and discussed. This new type of zinc foams has ideal threedimensional texture. Its porosity is higher than 80%. Most of the pores are open. They can be used as zinc electrodes in batteries.
