  • In the diamond powder manufacturing industry, the large stock of fine-grained diamond powder is one of the challenges. In this experiment, aluminum-borosilicate bond was used as the binder, and Si powder and Ti powder were used as additives to adjust the agglomeration effect of diamond abrasives. The bending strength, phase composition and micro-morphology of the samples were analyzed, the results showed that either the binder with Si or Ti additives would made agglomerated diamonds. When the mass content of Si and Ti was 10%, both the ceramic bond samples and the agglomerated diamonds had the highest bending strength, 43.74 MPa. When the content of Si or Ti exceeded 10%, many Si or TiO2 peaks were found in the sample, and the bending strength decreased sharply. The agglomerated diamond samples with Si had the bigger and more uniform particle size than the samples added with Ti. The particle size of agglomerated diamond samples with Si was 5~10 μm.
