Sol-gel techniques are interesting for the synthesis and processing of fine particles if the problems of stabilization of colloidal particles, their agglomeration and the fabrication of green bodies with high density are solved. A new approach for th

The effect of alumina precursors on microstructure, sintering and creep behavior of sol-gel derived mullite ceramics was studied by scanning and transmission electron microscopy (SEM, TEM and HRTEM), dilatometry and measuring the creep resistance in

The use of nanoparticles in hybrid and polymeric matrices has been investigated. Different types of nanocomposites have been prepared. The ormosil type based on organoalkoxy silanes shows surprising properties with respect to solid content and relaxa

For the first time a silylated spirooxazine was introduced into organically modified ceramics (Ormocer) coatings by the sol-gel method and its photochromic properties are studied and compared with the free (non-silylated) spirooxazine. The results re

Chemical synthesis has been used to fabricate polymerisable nanoparticles. Agglomerate free, well crystallised particles have been obtained by hydrothermal treatment and by using surface modifiers. Polymerisable liquids are used as modifiers to obtai

The sol-gel process allows the preparation of glasses and composites with homogeneities sufficient for optical applications, since phase dimensions can be kept below the level of undesired Rayleigh scattering. This is of special importance for inorga

We report on investigations of laser-induced crystallization of PbZr0.3Ti0.7O3 (PZT) gel-powder. By means of micro-Raman spectroscopy, and of optical and scanning electron micrography (SEM), we show that, upon laser irradiation, amorphous PZT materia

The sol-gel process can be considered as a method for the preparation of non-metallic inorganic materials by a chemical route. This general definition, however, does not match completely the specifics of this process since the sol phase is considered

Sol-gel technologies represent a powerful tool for making almost all kinds of transparent materials with interesting optical or photonic properties. During the last two decades, a large number of materials, mainly in form of coatings, have been devel
