The 90% premix was first mixed with the nano-silica powder and then the remaining premix was added. Since the viscosity of the glass slurry with a solid loading of 60 wt% was higher in the mixing process, the three-step mixing method (as shown in Fig. 4 (c)) was applied. Firstly, 90% nano-silica powder was dispersed into the 90% premix, and ...
