The LPG gas sensing response of polyethylene oxide ( PEO )- Cu ( Cu = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 and 1.0 wt. %) composite thick films prepared on alumina substrates by using novel screen printing technique are reported in present paper. The gas sensing responses of films were tested at 1000 ppm of LPG by using home-built static gas sensing system [between room temperature - 50 °C]. A very high value of SF = 1400 was obtained at an optimum temperature of 47 °C for a film with Cu = 0.7 wt.%. Further, better LPG sensing response, SF = 700 was obtained at low operating temperature = 36 °C for a film with Cu = 0.2 wt. %. The LPG sensing responses of the films were found to be strongly influenced by concentration level of Cu additive.

We report here on the preparation of La2/3Sr1/3MnO3 magnetoresistive thick films on polycrystalline Al2O3 substates by using the screen printing technique. It is shown that films can be obtained using high temperature sintering. While there is a reacted layer, this improves adhesion and is not too troublesome if the films are made thick enough. It is shown that PbO–B2O3 –SiO2 glass additives allow sintering at lower temperatures and can be used to improve the mechanical stress of the films. However, it is found that glass concentrations large enough to significantly improve the film adherence result in a weak low field magnetoresistance probably because grains are coated with high resistivity material. Strategies to overcome these difficulties are discussed.

The barium titanate (BaTiO3) thick films were prepared by screen printing technique using powders obtained by soft chemical route, modified Pechini process. Three different barium titanate powders were prepared: i) pure, ii) doped with lanthanum and iii) doped with antimony. Pastes for screen printing were prepared using previously obtained powders. The thick films were deposited onto Al2O3 substrates and fired at 850?C together with electrode material (silver/palladium) in the moving belt furnace in the air atmosphere. Measurements of thickness and roughness of barium titanate thick films were performed. The electrical properties of thick films such as dielectric constant, dielectric losses, Curie temperature, hysteresis loop were reported. The influence of different factors on electrical properties values was analyzed.
