Compacts of silica micro-spheres prepared for different times at sintering temperatures of 640 °C and 740 °C have been studied by Ultra Small-Angle Neutron Scattering (USANS) and Scanning Electron Microscopy (SEM). Stress versus strain measurements display several breakage points related to a range of nearest neighbour coordination around each microsphere.
