Abstract

New BiSrCaCu2Oyand Bi1.3SrCaCu2Oyoxide glasses were produced by the single roller melt-spinning technique. The glasses were found to translate into a supercooled liquid accompanied with a distinctly appreciable glass transition at about 680 K, followed by crystallization at about 725 K. The increase in Bi content brought about a decrease in glass transition temperature and an increase in crystallization temperature, i.e. the extension of the supercooled liquid region. Specific heats of the glassy solid and the supercooled liquid and the difference in specific heat between the two states were measured for the two oxide glasses.
