Sintering of Spherical Glass Powder under a Uniaxial Stress
Green, David J. and Halloran, John and Johnson, David W. and Klein, Lisa
The sintering of spherical borosilicate glass powder (particle size 5 to 10 μm) under a uniaxial stress was studied at 800°C. the experiments allowed the measurement of the kinetics of densification and creep, the viscosities for creep and bulk deformation, and the sintering stress which was found to increase with density. the data show excellent qualitative agreement with Scherer's theory of viscous sintering. in addition, the quantitative comparison between theory and experiment shows good agreement; the measured viscosity of the bulk glass was ∽1×109 P (∽1×108 Pa·s) compared to ∽3×109 P (∽3 Pa·s) obtained by fitting the data with Scherer's theory.
