The invention discloses a ceramic die for 3D glass hot-bending shaping and a method. The method includes following steps: (1), preparing and mixing: adding zirconium silicate powder, boron oxide powder, silicon carbide powder, nano carbon black powder and graphite powder into an alcohol solution according to a certain proportion, adding phenolic resin as a binder, and strongly stirring and mixingwell to obtain mixed slurry with certain viscosity; (2), drying, and sieving; (3), pre-shaping; (4), performing carbothermic reduction and high-temperature sintering: putting a pre-shaped graphite dieinto a hot-pressing sintering furnace for high-temperature sintering, wherein the highest sintering temperature is 1950-2150 DEG C, pressure is 20-50MPa, and temperature holding time is 1-2h. Zirconium silicate, boron oxide and nano carbon black are adopted as initial raw materials of boride, so that raw materials are extensive in source and low in cost. The defect that the graphite die is poor in anti-oxidation performance and non-resistant to wear is overcome, and service life is prolonged by more than three times.
