Li4SiO4 powder with a purity of 99.9% was fabricated by Alfa Aesar. PVA with a molecular weight between 31000 and 50000 manufactured by Sigma-Aldrich was used as binder material. PVA solutions prepared by dissolving PVA powder in distilled water with different
PVA amounts in the solution of 5, 10, and 15%. Li4SiO4 slurry was prepared by mixing Li4SiO4 powder and PVA solution.
