Solvothermal Synthesis of Advanced Composite Materials

Anotace

The Solvo-thermal technique is a chemical synthesis method used for the preparation of compounds with different morphologies. It has gained a lot of attention in recent years, and has been developed into an important solid-state synthetic method employing molecular solvents at intermediate temperatures (100-400)o C. The solvo-thermal technique uses organic solvents like ethanol, acetone, ethylene glycol, etc. to synthesize some powders. The morphology of the powder depends on the solvent used, reactants´ concentration, temperature and the solution´s pH. However, when the solvent used is water, the name used is hydrothermal synthesis - which is mostly used in literature. It was used to synthesize a well-crystallized, fine oxide powder, with uniform shape and narrow particle size distribution, without using a very high post-treatment temperature.
