Study of the hydration of coprecipitated in the preparation of PZT
Description
Coprecipitated PZT 53/47 was prepared through simultaneous precipitation of the cations (Pb+2, Zr+4 and Ti+4), in a solution of chloridric acid, using ammonium hidroxide. Two methods were tested ''to dehydrate'' the coprecipitated material: conventional calcination and using a satured solution of sodium hidroxide followed by conventional calcination. The second method possibilitate to obtain PZT 53/47 with only the rhombohedral phase. (author)
