Embodiment 1
[0036] According to the stoichiometric molar ratio of 1:1:1, Zr powder, Ni powder and Sn powder with a purity greater than 99.9% were weighed, mixed evenly, and then cold-pressed into a columnar body with a uniaxial pressure of 5 MPa and a holding time of 15 minutes to obtain a diameter of 40 mm. , 20mm high columnar green body;
[0037] Place the cold-pressed green body in a quartz mold, place the mold at one end of the centrifuge in a steel reaction chamber, place a tungsten coil as an ignition medium on the upper surface of the green body, and pump the reaction chamber to a vacuum of 10 -3 Pa;
[0038] Turn on the high-speed rotation of the centrifuge, set the gravity field to 1500G, and burn the tungsten wire spring coil under the supergravity field to ignite the green body to produce a combustion synthesis reaction;
[0039] After the reaction is over, continue to apply the supergravity field for 10 minutes;
[0040] The supergravity field was removed, and the sample wa...
