Abstract

Lanthanum nickel oxide (LNO) is a conducting ceramic which has potential to be used as electrodes in multilayer ceramic actuators. Thick LNO films have been formed by incorporating nanosized LNO powder (annealed at 700°C, with diameter around 100 nm) into a LNO solution prepared by a metal-organic decomposed ( MOD ) method. Three different weight percents, 2%, 4%, and 10% of LNO powder have been added. The structural variation of the ceramic/ceramic composite film with annealing temperature was studied by X-ray diffraction and differential thermal analysis. The crystallization temperature of the film is found to decrease from ∼590°C to ∼510°C due to the seeding effect introduced by the nano-powder.
