EXAFS measurements were done on Bi2Sr2CaCu2O8glass and glass‐ceramic to study the local environment of copper and strontium. X‐ray absorption measurements at the Cu K‐edge indicate that copper atoms are surrounded by four oxygen atoms in the glass and six oxygens in the glass‐ceramic with Cu‐O bond distances of 1.83 A˚ and 1.91 A˚, respectively. Measurements at the Sr K‐edge indicate that the Sr‐O distance in the glass‐ceramic is 2.70 A˚ with a coordination of nine.
