Description

technical field [0001] The invention relates to the technical field of vitrified binders, in particular to a high-performance boronium-barium-lithium glass material and a preparation method thereof. Background technique [0002] Vitrified bond is a substance made of low-melting vitrified material. It has good chemical stability, small elastic deformation, and wide range of hardness. Therefore, it is widely used as a mold bond in the manufacture of ordinary abrasives. The main components of the vitrified bond are glass materials (silica, boric acid, zinc oxide, barium oxide, spodumene, etc.), clay, colorants, binders, etc., which are mixed with diamond abrasives, formed and sintered at high temperature, and firmly bonded with the substrate. Combined to get a diamond abrasive tool. The vitrified bond in the prior art has high brittleness and poor impact resistance, thus limiting its wide application in certain applications. The glass material composition in the vitrified bon...
