[0024] Vitrified bond and its preparation method embodiment
[0025] The preparation method step of vitrified bond of the present invention is:
[0026] Material preparation step: prepare raw materials according to the components and contents in Table 1, wherein the particle size of ultrafine silicon dioxide is not greater than 5 microns;
[0027] Drying step: Put the prepared raw materials into an oven and keep them warm for 3 hours at 300 degrees Celsius;
[0028] Ball milling step: Put the heat-preserved raw materials into a star ball mill or a high-energy ball mill, mill at 300 rpm for 5-6 hours, and cool to room temperature;
[0029] Screening step: pass the cooled raw material through a 180-mesh sieve;
[0030] Repeat the above ball milling steps and sieving steps until all raw materials pass through a 180-mesh sieve.
