Preparation method of nano-scale hexagonal boron nitride/silicon dioxide multi-phase ceramic material
The invention discloses a preparation method of a nano-scale hexagonal boron nitride/silicon dioxide multi-phase ceramic material, and belongs to the technical field of ceramic materials. The preparation method comprises the following steps: performing oxidation treatment on hexagonal boron nitride powder at 400-800 DEG C; mixing the hexagonal boron nitride powder after the oxidation treatment with silicon dioxide powder; performing ball milling, stirring, pelleting, tabletting and rubber discharging; then sintering at 1500-1600 DEG C in an atmosphere furnace; and cooling to obtain the nano-scale hexagonal boron nitride/silicon dioxide multi-phase ceramic material. The preparation method disclosed by the invention is simple to operate and has low equipment requirements, the multi-phase ceramic material prepared by the method is good in compactness, bending strength and fracture toughness.
