摘要：

Thermodynamic calculations predict, and experiments verify, that YBa2Cu3O7-delta (123) powder is unstable in the presence of NOx-containing aerosol reactor exhaust gases at temperatures below about 600-degrees-C. Powders collected above the stability temperature are single-phase 123, while powders collected at lower temperature contain Ba(NO3)2 formed by reaction of the powder with NO(x) after exit from the hot zone.
