Abstract:
A ceramic-based toughness-enhanced material includes the following starting materials by volume percentage: 92-96% ceramic substrate powder, 2-4% single crystal sapphire fiber, 0.3-0.4% ceramic substrate disperser, 0.6-0.7% single crystal sapphire fiber disperser and 3-5% sintering aid.

Claim (Index 7):
A preparation method for the ceramic-based toughness-enhanced material based on single crystal sapphire fiber comprising\n weighing the ceramic substrate powder and the single crystal sapphire fiber; adding the ceramic substrate powder into a first reaction container, and adding the single crystal sapphire into a second reaction container; adding the ceramic substrate disperser into the first reaction container, and stirring at a high speed and carrying out ultrasonic treatment to obtain a uniformly dispersed first suspension; adding the single crystal sapphire fiber disperser into the second reaction container, and stirring at a high speed and carrying out ultrasonic treatment to obtain a uniformly dispersed second suspension; dropwise adding the second suspension into the first suspension, and stirring at a high speed such that the first suspension and the second suspension are sufficiently mixed to obtain a third suspension; vacuum filtering and drying the third suspension to obtain a mixed powder; and adding the mixed powder and the sintering aid into a graphite mold for hot-pressing sintering to obtain the ceramic-based toughness-enhanced material.
