AB  - Pseudobrookite thick films were obtained by screen printing paste composed of a 1: 1.5 molar ratio mixture of starting nanopowders of hematite and anatase, glass frit and organic binder. The films were deposited on alumina substrates with interdigitated electrode geometry. Sintering at 850 degrees C resulted in the formation of pseudobrookite. X-Ray Diffraction (XRD) analysis showed pseudobrookite with a mixed orthorhombic and monoclinic structure and a small amount of excess rutile. Gas sensing measurements with low NO gas concentrations in air were performed using an in-house gas sensor testing setup in the temperature range 100300 degrees C. On the example of one particular gas concentration, results showed that pseudobrookite exhibited a distinct response to NO already at 150 degrees C that further improved with increased sample temperature.

AB  - Two pseudobrookite (PSB) containing pastes were composed of a mixture of starting nanopowders of hematite (alpha-Fe2O3) and anatase (TiO2) in the molar ratios 1: 1 (referred to as PSB-1) and 1:1.5 (referred to as PSB-1.5), respectively, organic vehicle and glass frit. The pastes were screen printed on alumina (Al2O3) substrates and sintered in a hybrid conveyor furnace at 850 degrees C/10 min in air. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis showed that the resulting thick film samples were composed of pseudobrookite (Fe2TiO5) and also excess rutile (TiO2) in the case of PSB-1.5 samples with a small grained and relatively homogenous microstructure. An electric resistivity with negative temperature coefficient (NTC) was observed. An interdigitated electrode geometry was designed and different electrode spacing (0.2 and 0.25 mm) was analyzed. The electrode structure was printed of PdAg paste. The resistivity of pseudobrookite was measured and analyzed in view of possible applications as a sensor of environmental gases with sufficiently high sensitivity at operating temperatures lower than conventional gas sensor systems.

AB  - If the material is being sintered, grain size of its particles will depend on the sintering temperature, time of the sintering and the pressure applied on the material while sintering. It is well known that on the lower sintering temperatures grain size of the nano material is relatively small and thus the active area is large. Due to the low sintering temperature, high material porosity is expected as well. With a decrease of grain size, gas sensitive materials have larger selectivity, higher sensitivity, sensor response increases steeply and they are more immune to poisoning. The core of the investigation is to observe the influence of sintering temperature on grain size of the TiO2 nano-paste and to determine its reflection on the material porosity. For the realization of gas sensors using Low Temperature Co-Fired Ceramic (LTCC) or High Temperature Co-Fired Ceramic (HTCC) technology, specimens have to be sintered at relatively high temperatures. For the first interaction, custom-designed TiO2 nano-paste has been deposited on a sintered alumina (Al2O3) substrates using screen printing. Specimens have been sintered at peak temperatures in a range of 800 degrees C - 1500 degrees C for 30 minutes and afterwards they have been characterized with Scanning Electron Microscopy (SEM) and energy dispersive x-ray spectroscopy EDS.
