The book chapter describes microstructural features found in advanced functional ceramic materials and advanced analytical methods used for their investigation. The described features and methods are partially based on experience gained through the implementation of the project.

With the application of an oxygen atmosphere, we synthesized a highly textured sodium cobaltate. At the same time, we identified its peculiarities that influence the measured parameters to a degree that seriously questions this material’s potential for use. We have systematically studied the influence of humidity on the ceramic pellets and found the conditions under which the material completely deteriorates. By performing microstructural and thermal analyses, coupled with a determination of the evolved gases, we identified the chemical reactions that are involved in this process.

We demonstrate the potential of highly oriented zinc oxide (ZnO) films grown on glass substrates under low-temperature hydrothermal (HT) conditions at 90 °C from aqueous solutions of Zn-nitrate and Na-citrate. Formation of a continuous ZnO seed-layer with proper thickness, grain size, connectivity, and orientation of seed-grains on glass is shown to be essential to achieve conditions for the growth of highly oriented (0001), smooth, transparent, and conductive ZnO films according to the spatially confined oriented growth (SCOG) mechanism. The film grown on homogeneous seed-layer with grain size of about 20 nm showed optical transmittance of up to 82% and relatively low resistivity.
