“…In comparison, the sintering temperature of the stacked abrasives in our study decreased by approximately 100 °C, while the compressive strength increased by about 10 N. This also indicates the advantages of using the sol-gel method to prepare low-temperature vitrified bond. Cao et al [33] also prepared the vitrified bond and stacked abrasives using melt quenching and molding and crushing methods, respectively, and in their study the compressive strength of the corundum stacked abrasives could be maintained at 26 N at a sintering temperature of 760 °C. Although the sintering temperature of the stacked abrasives decreased by approximately 60 °C compared to our study, the vitrified bond used in their research is a six-component oxide system.…”

Currently, the sol-gel technique is employed in the synthesis of high-performance vitrified bonds; however, its application in the fabrication of stacked abrasives has been minimally explored. Furthermore, the methods utilized in the production of abrasive particles for stacked abrasives are technically challenging and incur high costs, which hinders their actual industrial application. Consequently, this study utilizes the sol-gel approach to synthesize a Na2O-B2O3-SiO2 ternary system vitrified bond powder and employs a molding and crushing method, which offers a lower technological barrier and reduced preparation costs, for the production of abrasive particles subsequently fabricating corundum stacked abrasives. Upon setting the binder composition to a molar ratio of n(SiO2):n(B2O3):n(Na2O) = 65:23:12, it was observed that the crystallization within the glass matrix was minimized and the optimal sintering temperature for the synthesized laminate abrasive to be sustained at 820 °C. At the aforementioned temperature, the binder melt is capable of flowing uniformly amongst the abrasive granules, thereby ensuring a robust encapsulation of the particles. The average single particle compressive strength of the prepared corundum stacked abrasive with a grain size of forty mesh can reach the highest of all composition points at 28.56 N and the average single particle compressive strength of the prepared diamond stacked abrasive is 28.14 N.
