Embodiment 1
[0032] Under vacuum conditions, lithium hydride and molybdenum trioxide were mixed in a molar ratio of 6:1, placed in a heating furnace, raised to 400 °C at a heating rate of 5 °C / min, and reacted for 2 h. After the heating is completed, the solid product is taken out, soaked in deionized water, washed, centrifuged to separate the solid product, and dried under normal pressure to obtain uniformly dispersed metal molybdenum nanoparticles.
[0033] figure 1 For the X-ray diffraction pattern of the product prepared in Example 1, figure 2 Scanning electron micrograph of the product prepared for Example 1. from figure 1 It can be seen that the position of the diffraction peak of the sample completely corresponds to the PDF#-42-1120 card of molybdenum, indicating that the present invention successfully prepares nano-metal molybdenum powder. pass figure 2 It can be seen that the prepared metal molybdenum particles are ellipsoid, the size distribution is 30-50 nm, the morphology...
Embodiment 2
[0035] Under an argon atmosphere, lithium hydride and tungsten trioxide were mixed in a molar ratio of 6:1, placed in a heating furnace, raised to 550 °C at a heating rate of 10 °C / min, and reacted for 4 h. After heating, the solid product is taken out, soaked in deionized water, washed, centrifuged to separate the solid product, and vacuum dried to obtain uniformly dispersed metal tungsten nanoparticles.
[0036] image 3 For the X-ray diffraction pattern of the product prepared in Example 2, Figure 4 Scanning electron micrograph of the product prepared for Example 2. from image 3 It can be seen that the position of the diffraction peak of the sample completely corresponds to the PDF#-47-1319 and PDF#04-0806 cards of tungsten, indicating that the present invention successfully prepares nano-metal tungsten powder. pass Figure 4 It can be seen that the prepared metal tungsten particles have a size distribution of 50-100 nm.
Embodiment 3-8
[0038] Lithium hydride and metal oxide powder are mixed and placed in a heating furnace to heat up the reaction. After the reaction is completed, the sample is cooled, and the solid product is taken out and soaked in deionized water, washed, centrifuged and dried to obtain nano metal powder. Each process parameter is implemented according to Table 1.
