Embodiment 1
[0054] In this embodiment, atomic layer deposition technology is used to coat zirconia with a thickness of 100 cycles (about 10 nm) on the surface of nano-aluminum powder to passivate the aluminum powder. The method includes the following steps:
[0055] (1) Weigh 0.2 grams of nano-aluminum powder with an electronic balance, put it into a holder with a filter screen at the bottom, then put the powder holder into the cavity of the atomic layer deposition reactor, and cover the cavity , turn on the switch of the vacuum pump to vacuumize, and the outlet pressure of the cavity is 1Pa.
[0056] (2) Heating the chamber, the temperature of the reaction chamber is set at 150°C. During the heating process, nitrogen gas is continuously fed in at a flow rate of 100 standard milliliters per minute as the fluidization gas to pre-disperse the aluminum powder, and the outlet of the chamber is The pressure is 40Pa;
[0057] (3) When the temperature of the chamber is stable at 150°C, the atom...
Embodiment 2
[0065] In this embodiment, atomic layer deposition technology is used to coat zirconia with a thickness of 10 cycles (about 1 nm) on the surface of nano-aluminum powder, and the aluminum powder is passivated. The method includes the following steps:
[0066] (1) Weigh 0.05 grams of nano-aluminum powder with an electronic balance, put it into a holder with a filter screen at the bottom, then put the powder holder into the cavity of the atomic layer deposition reactor, and cover the cavity , turn on the switch of the vacuum pump to vacuumize, and the outlet pressure of the cavity is 0.5Pa.
[0067] (2) Heating the chamber, the temperature of the reaction chamber is set at 120°C. During the heating process, nitrogen gas is continuously fed in at a flow rate of 50 standard milliliters per minute as the fluidization gas to pre-disperse the aluminum powder, and the outlet of the chamber is The pressure is 200Pa;
[0068] (3) When the temperature of the chamber is stable at 120°C, t...
Embodiment 3
[0076] In this embodiment, atomic layer deposition technology is used to coat the surface of nano-aluminum powder with zirconia with a thickness of 1000 cycles (about 100nm) to passivate the aluminum powder. The method includes the following steps:
[0077] (1) Weigh 5 grams of nano-aluminum powder with an electronic balance, put it into a holder with a filter screen at the bottom, then put the powder holder into the cavity of the atomic layer deposition reactor, and cover the cavity , turn on the switch of the vacuum pump to vacuumize, and the outlet pressure of the cavity is 0.8Pa.
[0078] (2) Heating the chamber, the temperature of the reaction chamber is set to 180°C. During the heating process, nitrogen gas is continuously fed in at a flow rate of 500 standard milliliters per minute as the fluidization gas to pre-disperse the aluminum powder, and the outlet of the chamber is The pressure is 500Pa;
[0079] (3) When the temperature of the chamber is stable at 180°C, the ...
