Viscous sintering Scherer model

Figure 13. Sintering parameter (1/K) and viscosity according to Scherer model (85) of viscous sintering for two-step acid-catalyzed xerogel. Samples were heated to indicated temperatures at 2 or 20 °C/min and held isothermally. Corresponding bulk densities are plotted on the abscissa. (Reproduced with permission from reference 79.

Figure 8.15 Scherer s model for viscous sintering, (a) Unit cell of the structure with edge length I and cylinder radius a. (b) Microstructure with a relative density of 0.1. (c) Microstructure with a relative density of —0.5. (From Ref. 21.)...

Derive Eq. (8.51) for the volume of the solid phase in a unit cell of Scherer s model for viscous sintering. 

Figure 11.33 Isothermal shrinkage data for constrained and free glass films sintered at 650°C. The curve through the data for the free film represents the best fit to the data using Scherer s model for viscous sintering. The curve through the data for the constrained film represents the fit to the data by the thin-fihn model of Scherer and Garino using the fitting constants derived from the fit to the free-film data. (From Ref. 47.)...
