Microstructure and Glass Phase of Inorganic Binder Coated on Mold for Thin Casting
Figure 4
SEM morphologies on the fracture surfaces of mold samples through process II as a function of SiO2 precursor: (a) TEOS and (b) PDMS. Each number indicates SEM morphologies before and after the heat treatment, respectively. Dotted and solid arrows indicate the crack created (series-1) and glass phase formed (series-2) in mold samples, respectively.
