Abstract

The invention discloses a microcrystalline glass binder, a preparation method of the microcrystalline glass binder, a superhard material grinding tool and a preparation method of the superhard material grinding tool, and belongs to the technical field of superhard material tools. The microcrystalline glass binder is prepared from, by mass, 55-65% of SiO2, 5-15% of CaO, 1-10% of K2O, 5-15% of Na2O and 5-20% of CaF2. The superhard material grinding tool is prepared through the microcrystalline glass binder, and lath-shaped anisotropic crystals exist in the microcrystalline phase of the superhard material grinding tool and are distributed in a cross mode. According to the preparation method of the superhard material grinding tool, the crystallization temperature in the sintering process is controlled, so that lath-shaped anisotropic crystals exist in the microcrystalline phase of the superhard material grinding tool and are distributed in the cross mode, and the preparation method is easy, convenient and applicable to industrial production.
