Homogeneous nucleation versus glass transition temperature of silicate glasses

This paper provides experimental and theoretical evidence for a correlation between the maximum internal nucleation rate, I-max = I(T-max) [where T-max is the temperature of maximum nucleation rate] and the reduced glass transition temperature, T-gr, for 51 glass-forming liquids. In addition, it demonstrates an analogous correlation between T-max, the time-lag of nucleation at T-max and the reduced glass transition temperature. An explanation is given for these remarkable trends. (C) 2003 Elsevier Science B.V. All rights reserved.
