The effects of different firing temperatures on the stability of perovskite phase, grain size, and dielectric properties were investigated by XRD, TEM, SEM and dielectric measurements. The dielectric ceramics of Pb(Mg1/3Nb2/3)O3-PbTiO3-BaTiO3 system were obtained by chemical coprecipitation in water. The ceramics have higher dielectric constant (7003-9714), lower firing temperature (950-1150℃), quite uniform microstructure with grain size less than 2.5μm, and lower temperature coefficients of capacitance. As a result, it was confirmed that the simple and low cost chemical route used namely coprecipitation in water is a desired meth-od for preparing high property dielectric materials applicable to multilayer capacitors

The physico-chemical behavior of rare earth elements in low sulphur 16Mn steel and their ability to enhance the corrosion resistance of the steel in sea water studied in this paper. The results indicate that Ce and La in 16Mn steel all have the abilities such as deoxidation, desulphidation, refining grains and cleaning grain boundaries and matrix etc. The anodic and cathodic polarization curves show that the rare earth elements added in 16Mn steel enhance the corrosion resistance of the steel in sea water
