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.

AB  - The delafossite CuAlO2 powder was prepared from the nano-boehmite AlOO center dot xH(2)O and Cu2O by the solid state synthesis at 1100 degrees C in argon. The inherently slow solid state reaction was accelerated by introducing rod-like boehmite nano-particles which fully covered the 1 mu m sized Cu2O particles in the reactant mixture, and decomposition of the nano-boehmite upon calcination. In contrast, the reaction between the Cu2O and Al2O3, introduced as a reference, resulted in mixed phases under the same experimental conditions. Sintering of the nano-boehmite derived CuAlO2 powder compact at 1100 degrees C for 2 h in air resulted in the delafossite ceramic with 86% of theoretical density, without any impurities detectable by X-ray diffraction analysis. The analysis of the microstructure by scanning electron microscopy confirmed that the bulk of the sintered sample was delafossite phase with uniformly distributed porosity, with only traces of Cu-rich impurities at the surface.
