Study on Dependability and Repeatability of Measurement Method of Mean Linear Thermal Expansion Coefficients of Glasses

Abstract:

Coefficient of mean linear thermal expansion is an important physical property of glasses. It is the key thermodynamic property to evaluate the thermal stability and matching sealing of glasses. The measurement results of coefficient of mean linear thermal expansion obtained by different dilatometers showed that glass expands slowly with nonlinearity below 50 °C. It suggested that the initial temperature of measurement would be set above 50 °C, as behaves better repeatability and reliability of measurement than 20 °C as standard method set.
