[0016] First, weigh 6g of silicon oxide whiskers, 3g of titanium oxide whiskers, and 8g of silicon carbide whiskers in sequence, add them to a ball mill, then add 100mL of deionized water, and ball mill with zirconium balls for 2 hours to obtain a slurry, and place the slurry in Dry in an oven at 95°C for 6 hours to obtain powder; then weigh 5g of glass, pulverize it with a pulverizer, and sieve to obtain a 100-mesh powder. Add the glass powder into a beaker, add the above powder into the beaker, and stir for 5 minutes. The mixed powder is obtained, and the mixed powder is added to the high-pressure reactor, the temperature is controlled at 700°C, the pressure is 20MPa, and the reaction is stirred for 4 hours to obtain the reactant; the above reactant is added to the flask, and the flask is placed in an ice-water bath , control the temperature at 0°C, stir for 20 minutes to obtain a solid, put the solid in an oven at 95°C and dry for 2 hours to obtain nanostructured ceramics; a...
