Studies on high-T_c superconductor Ba_2YCu_3O_(6.92) using thermogravimetry, temperature programmed decomposition, oxygen isotopic exchange method are reported. There are six steps in the thermogavimetric graph of Ba_2YCu_3O_(6.92). At the first step, 0.40 oxygen atom per unit cell is released, the amount of which corresponds to that of the oxygen released from the CuO_4 square plane when the oxidation number of copper reduced from +3 to +2. This amount of oxygen plays a key role on the influence on the T_c of superconductor. At the is 0.45, corresponding to the amount of oxygen released from CuO_4 when the oxidation number of copper changed from +2 to +1. The oxygen atom released totally at the last three steps is 1.07 per unit cell, which correspondes to the oxygen released from CuO_5 square pyramid when the oxidation number of copper changed from +2 to +1. The first three steps are almost continuous, so in TPD curve there is only one peak at 514 ℃ with respect to the three steps in TG curve and the decomposition heat of this one is 171±8 kJ mol~(-1). Another peak which is over 900 ℃ on TPD curve is the result of the loss of oxygen from the last three steps in TG curve. The sample released oxygen can recover its supeconductivity after reabsorbing oxygen. Oxygen isotopic exchange method shows that the oxygen atoms of CuO_4 and CuO_5 groups can be interexchanged under certain temperature and indicates that there is some bonding between CuO_4 square plane and CuO_5 square pyramidal groups in the crystal lattice of Ba_2YCu_3O_(6.92).
