ABSTRACT
The chapter presents the comparative analysis of the sol-gel (SG) and solid-state reaction (SSR) routes to synthesize thallium-based superconductors. 150Samples were prepared by a two-step method and by sealed quartz tube technique in ambient pressure. We could conclude that using wet chemistry offers some advantages compared to the classical solid-state ceramics processing, significantly better chemical homogeneity, and higher reactivity of the precursor powder.
