摘要：
The phase Bi2O2Te exists in the pseudobinary system Bi2O3/Bi2Te3. The thermal behaviour of Bi2O2Te was determined by DTA and X-ray analysis: The phase exists up to 620 degrees C and decomposes into the solid phases Bi12TeO20, Bi10Te2O19 [1] and liquid BiTe. The relations of the phase coexistences in the pseudobinary system and in the ternary area Bi2O3/TeO2/Bi2Te3/Te were investigated by solid state reactions, chemical transport reactions, and by total pressure measurements.
