    Notizen: Abstract SiO2 gels obtained by sonocatalytic method combined with DCCA were used as host-matrices for extremely fine dispersions of CdS semiconductor particles. Small crystallites were produced “in situ” by H2S gas diffusion method. The particles were characterized by TEM and HRTEM, EXAFS, UV-Vis and Raman spectroscopies. The size of crystallites ranged from 5 to 10 nm. The optical transmission spectra showed the characteristic blue shift as a function of the particles size, as predicted by the theory. The optical and mechanical qualities of the samples were substantially improved by an infiltration method using a sono-sol which sealed the superficial pores thus ensuring greater longevity and the possibility of obtaining transparent gels by polishing.

    Notizen: Abstract Amorphous zirconia ceramics powders containing 3 and 6 mol% yttria were prepared by controlled hydrolysis of alkoxides. Characterization of these powders was carried away by Thermal Analysis, X-ray Diffraction, Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDAX™). The calcination temperature was optimized for compaction at a temperature ranging from 500–800°C. 3% molar YSZ powders from alkoxide, that attained 98% of the theoretical bulk density, showed the best behaviour.
