Abstract
This paper presents possible applications of thermal analysis and sorptomatic methods to study physico-chemical properties of the high-T csuperconductor Y1Ba2Cu3O7-x and perovskite LaCoO3. It is shown that both Y1Ba2Cu3O7-x and perovskite phase are highly sensitive to water vapour. Mechanism of adsorption of water on LaCoO3depends largely on time activation (t act). When the time of water vapour saturation was 0<t act<180 s, physisorption process was observed. In the case of longer times water vapour action, t act>180 s, chemical decomposition was observed.
