Ceramic Oxide (MeO2) Solid Solution Obtained by Mechanical Alloying

This work has to be regarded as a laboratory study concerning the synthesis and the application as ceramic pigments of powders obtained by mechanochemistry. In ceramic industry pigments, that must show thermal and chemical stability at high temperature and must be inert to the chemical action of the molten glazes, were traditionally obtained by calcination of raw materials. These heat treatment was carried out adding mineralizers (fluorides) to lower the high synthesis temperatures (1200-1400°C). The possibility to obtain them at room temperature and without mineralizers is of great interest: avoiding high calcination temperatures can cause dramatic reduction in toxic gase emission and minimizes high temperature technology investments.
