  • A co-precipitation procedure for the synthesis of LSM material = Sobarjanje LSM za pripravo katodnih materialov za gorivne celice
    Marinšek, Marjan, kemijski inženir ...
    Lanthanum manganite substituted with strontium is a strong candidate for use as a mixed conductor at the cathode site in solid-oxide fuel-cell systems. In the present work a co-precipitation method ... for the preparation of LSM is described and some material properties are reported. Since the co-precipitation involved calcination at 1000 °C and subsequent sintering, the crystalline phase development and the material homogeneity were followed by X-ray powder diffraction. It was found that no secondary crystalline phases were present in the system when the samples were thermally treated up to 1200 °C. The sintering behaviour of the calcined powders and their density evolution are also reported. Relatively dense bodies were prepared after thermal treatment at 1200 °C for 2 hours. The electrical characteristics of the material were determined from screen-printed LSM sintered layers. The electrical conductivity of the screen-printed layers increased with the sintering temperature due to an additional densification effect. Porous LSM bodies were prepared by methyl cellulose admixing as a pore-former.
