Viscosity of LTCC Determined by Discontinuous Sinter-Forging
Abstract:The sintering behavior of the commercial material Ceramtape GC, a glass-ceramic composite, is characterized with the help of the continuum mechanical description. The sinter-forging technique permits to determine the uniaxial viscosity of the porous ceramic body as a function of density. At an isothermal temperature of 840°C, the uniaxial viscosity varies from 0.2 to 6 GPa.s with increasing relative density from 76% to 97%. Continuous and discontinuous sinter-forging allows the characterization of the effect induced by the load.
