Popis:	The effect of C content on the decomposition temperature of Bi2Sr2CaCu2O8 (Bi2212) with 0 and 10 wt.% added was investigated in atmospheres of 0.01,and 0.21 and 1.00 bar oxygen. The C content of the samples was controlled by a high-temperature heat treatment and subsequent exposure to H2O saturated air. It was found that an increase in C content from 30 ppm to 7000 ppm suppressed the decomposition temperature of Bi2212 by only 3°C independent of Ag content. Furthermore, it was found that the previously observed suppression of the decomposition temperature with the addition of Ag was unaffected by changes in the C concentration from 80 to 1500 ppm.
