Glass powder for low-temperature sintering MLCC terminal electrode slurry and preparation method thereof

The invention discloses glass powder for low-temperature sintered MLCC (multilayer ceramic capacitor) terminal electrode slurry and a preparation method of the glass powder. The glass powder comprises the following raw materials: 10%-40% of B2O3, 20%-50% of BaO, 5%-20% of ZnO, 2%-15% of SiO2, 1%-5% of Al2O3 and 10%-40% of TeO2. The preparation method comprises the following steps: uniformly mixing the raw materials according to the mass ratio, melting and quenching in a box-type high-temperature furnace at the furnace temperature of 1,200-1,300 DEG C to prepare glass, and grinding and sieving to obtain glass powder with the particle size of 1-2 mu m; the glass powder provided by the invention does not contain toxic lead elements, the sintering temperature is 650-750 DEG C, after the glass powder is sintered, the wettability with an MLCC ceramic matrix is good, the adhesive force is strong, the electrode at the sintering end is dense, the phenomena of cracking and etching are avoided after the glass powder is
