LIMA, Patrícia Tavares de; BERTRAN, Celso Aparecido and THIM, Gilmar Patrocínio. Routes of synthesis and the homogeneity of mullite and cordierite precursors. Quím. Nova [online]. 1998, vol.21, n.5, pp.608-613. ISSN 1678-7064. http://dx.doi.org/10.1590/S0100-40421998000500013.
Multicomponent ceramics are mainly synthesized by conventional solid-state reaction route and sol-gel routes. In the sol-gel route, colloidal or polymeric gel are envolved. In this work, some principles of the chemistry of theses routes are discused and it is ilustrated a variety of strategies for obtaining a homogeneous multicomponent precursors.
Keywords : homogeneity; multicomponent precursors; sol-gel.
