The invention relates to a ceramic compound bonding agent, in particular to a nano-ceramic compound bonding agent, which is suitable for manufacturing super-hard grinding tools with various granularity and belongs to the technical field of materials. The bonding agent is prepared by adding second phases, such as nano-grade granules, nano-grade lamellas, nano-grade whiskers, nano-grade fibers and the like to a ceramic bonding agent matrix to form a nano-compound material, wherein at least one phase of the nano-compound material is of nano-size. Because the of small granularity and large specific surface area, the nano-ceramic material presents evident small size effect, quantum size effect and surface interface effect, which ensures that the nano-ceramics have special properties different from traditional ceramics, such as high intensity, good tenacity, low sintering temperature and the like. Thus, when the nano-powder is adopted to carry out sintering, the densifying speed is high, the sintering temperature is lower and is 400-600 DEG C lower than that of the traditional ceramics manufacturing, and the sintering process is greatly shortened.
