[0064] Such as figure 1 As shown, the preparation method of the pot provided by the embodiment of the first aspect of the present invention includes:
[0065] Step S10: mixing powdery raw materials and making them micronano-scaled to form micro-nano-scale mixed powders, wherein the raw materials include ceramic powders and metal particles;
[0066] Step S20: putting the mixed powder of micro-nano scale into a mold for molding to obtain a green body of the pot;
[0067] Step S30: The green body is sintered and solidified in a furnace to obtain a pot.
[0068] In the preparation method of the pot provided by the embodiment of the first aspect of the present invention, by adding metal particles into the traditional ceramic pot, the fracture toughness of the ceramic pot is effectively enhanced, which solves the problem that the ceramic pot is easy to be knocked in the prior art. The problem of broken and broken, thus prolonging the service life of the ceramic pot; and because th...
Embodiment 1
[0108] Will Al 2 o 3 , SiO 2 The powder is mixed with metallic Ni particles at a content of 8%;
[0109] Use a ball mill to grind and mix the powder evenly, wherein ceramic balls are used for ball milling, the ball-to-material ratio is 1:1, and the ball milling time is 8 hours, so that the powders are all in the micro-nano scale;
[0110] Use mechanical mixing to disperse metal powder and ceramic powder evenly;
[0111] Then put it into a drying furnace for drying to prevent powder agglomeration, wherein the temperature of the drying furnace is 120°C, and the drying time is 8 hours;
[0112] Add the mixed powder into binder etc. for dry pressing molding, the molding pressure is 50kN, and the thickness of the formed pot body is 4mm;
[0113] Carry out high-temperature pressure sintering on the formed pot body, adopt a staged sintering temperature control method, keep warm at 120°C for 13 minutes——hold at 800°C for 13 minutes——pressurize at 1200°C (pressure is 8MPa)——hold at...
