Thermal solid-phase conversions of the yttrium-barium-copper salt of tricarboxycellulose (TCC) with a 1-2-3 cation stoichiometry, respectively, have been considered. Yttrium barium cuprate is the end product of the thermal treatment of the triple salt. According to the data of X-ray analysis the onset of 1-2-3 phase formation is noticeable at 750-800{degrees}C. The temperature 875{degrees}C (with a duration of heating of 12 h) is sufficient for practically complete conversion of the Y-Ba-Cu salt of TCC into YBa{sub 2}Cu{sub 3}O{sub 7-{delta}}.
