摘要:

以偏钛酸、双氧水、氨水、乙酸铅和硝酸锆为原料,乙二胺四乙酸(ethylene diamine tetraacetic acid,EDTA)为络合剂,柠檬酸为燃烧剂,采用凝胶燃烧法制备得到了锆钛酸铅(PbZr0.52Ti0.48O3,PZT)纳米粉体。首先,按相同摩尔比将偏钛酸溶于双氧水和氨水的混合溶液中,再加入适量的柠檬酸,得到棕红色透明溶液,向该溶液中加入由EDTA络合的等摩尔的Pb2+溶液与适量的Zr4+溶液,再将此混合溶液加热浓缩成胶状物后在不同温度煅烧,得到PZT纳米粉体。结果表明:PZT纳米粉体在400~500 ℃形成,将所得胶状物在700 ℃煅烧4 h,制得的PZT纳米粉体的粒径在50~150 nm之间。

Nano-powders of PbZr0.52Ti0.48O3 (PZT) were fabricated by a developed gel-combustion method using meta-titanic acid, hydrogen peroxide, ammonia, lead acetate and zirconium nitrate as raw materials, and ethylene diamine tetraacetic acid (EDTA) and citric acid as a complexing agent and an incendiary agent, respectively. H2TiO3 is firstly dissolved in a mixture solution of H2O2 and NH3·H2O with the same mole ratio, then the citric acid is added into the above solution, obtaining a brown-red transparent solution, which is added with the identical mole ratio of EDTA-complexed Pb2+ and Zr4+ solutions. The obtained mixture is heated and condensed into the gels before calcined at different temperatures to prepare nano-powders of PZT. The results show that the nano-powders of PZT from the gels forms at 400-500 ℃. The nano-powders of PZT in the grain size range of 50-150 nm can be obtained after calcined at 700 ℃ for 4 h.
