“…According to our previous research on phosphate-based inorganic adhesives [7], although they possess outstanding heat resistance, their lower bonding strength restricts their application. Generally speaking, the polymer adhesive can provide high strong joining after the polymer's ceramic conversion reaction [8,9]. However, since the polymer's strength was very low during the conversion process [10], as-received joints are always needed to be calcined at temperature above conversion temperature before being applied in practice, which reduces the polymer-based adhesive's practicability.…”
