Abstract:
PURPOSE: A nano-sized glass powder for sintering aid and a manufacturing method thereof are provided to have uniform particle distribution by using a sol-gel method. CONSTITUTION: A manufacturing method of A nano-sized glass powder for sintering aid comprises the following steps: dissolving starting raw material of boron(B), starting raw material of silicon(Si), and starting raw material of metal oxide in non-aqueous solvent in order to manufacture a mixture(s11); controlling a sol-gel reaction by adding alkali catalyst to the mixed solution(s12); and drying the sol-gel reagent and heat treating thereof(s13). The non aqueous solvent is ethanol. The heat treating is processed at less than 650 deg. Celsius. A manufacturing method of nano size glass powder for sintering aid uses the non aqueous solvent.
