The evaporation process of β-diketonate precursors for the MOCVD deposition of YBa2Cu3O7-x superconducting films has been investigated by thermogravimetric analysis. Special attention has been paid to the Ba(thd)2 precursor. A simple model of the reactions involved in this process has been described. YBa2Cu3O7-x superconducting layes were deposited on YSZ substrates by MOCVD in a horizontal hot-wall reactor. Films showed a mixture of c-axis and a-axis orientation and have a Tc(R=0)=88.2K and Tc onset=91.6K
