| 中文摘要 | We have studied the physical properties such as the viscosity, eta, density, rho, and surface tension, gamma, of Li2O-4B(2)O(3) melt at a high temperature of 860 degrees C up to 1150 degrees C in air ambient atmosphere. From the viscosity measurement, it has been found that the activation energy, E-a, of the melt, with slight relaxation, shows a distinct change around 970 degrees C. The existence of this anomalous point at around 970 degrees C was also clearly verified by the density and surface tension measurements. The temperature coefficients of these properties at low- and high-temperature side of the point are E-a: 150 kJ/mol, d rho/dT: - 5.54 x 10(-4) g/cm(3) K, d gamma/dT < 0 and E-a: 104 kJ/mol, d rho/dT: - 6.74 x 10(-4) g/cm(3) K, d gamma/dT > 0, respectively. Our results are informative for understanding the molten state of Li2O-4B(2)O(3) melt as well as helpful in growing LBO crystals. (C) 1999 Elsevier Science B.V. All rights reserved. |
