The obtained Kauzmann temperature is consistent to that calculated by Vogel-Fulcher law and by the melting points of the components ofthe alloy. During the measurements of the specific heat of the undercooled liquid, differentheating rates are utilized to enlarge the measuring temperature range nearby the glass transition temperature. Thus the reliability of the thermodynamic function of the undercooled liquid is increased. The possibility for the overheating of the crystal is studied by producing oxide films on the surface of the crystalline specimen.
