抄録
The effect of water vapor in a calcining atomosphere on Tc, off of YBa2Cu3O7-x was investigated using the electrical resistivity method, X-ray diffraction analysis and carbon analysis. The results are as follows:<BR>(1) The critical temperature(To, off) elevated with increasing H2O partial pressure, reached a maximum(90.5K) at a H2O partial pressure of about 5kPa, and then lowered.<BR>(2) The water vapor remarkably accelerated the decomposition of BaCO3. However, the excessive addition of water vapor was detrimental because of the formation of an unknown phase.
