Thick film ceramics of 8% mol doped‐ (8YSZ)‐ (LSGM) composite for solid electrolyte have been synthesized from nanopowder. Concentration of LSGM was 0 and 10% weight. A paste for the thick films was made from 8YSZ nanopowder prepared using sol gel method and LSGM powder prepared by solid state reaction. Precursors for the 8YSZ nanopowder preparation were derived from local zircon as byproduct of Tin processing at Bangka Island using caustic fussion method, and The thick films were produced by screen printing technique on alumina substrates. The films were sintered at 1500° C for 2 hours in air. X‐ray diffraction (XRD) data showed that the nanopowder of 8YSZ was well produced with broad peaks. The particle size of the 8YSZ powder was about 12 nm as calculated using Debye Scherrer method. The thick films of 8YSZ and 8YSZ‐LSGM (90:10 in weight %) composite could be produced, however, the films still contain voids. The ionic conductance of the YSZ‐10LSGM films was smaller than that of the YSZ films.
