Preparation method of high-entropy boride infrared radiation material
The invention relates to a preparation method of a high-entropy boride infrared radiation material, which comprises the following steps: taking four nitrates or sulfates in Co (NO3) 3.6 H2O powder, Ni (NO3) 2.6 H2O powder, Cr (NO3) 3.9 H2O powder, Cu (NO3) 2.3 H2O powder and FeSO4. 7H2O powder as raw materials and sodium borohydride as a boron source in a reaction container, respectively stirring and dissolving the raw materials and the boron source in deionized water which is subjected to nitrogen or argon purging for 40-80 minutes in advance, and then adding sodium borohydride into the raw materials and the boron source; and mixing the obtained salt solution with a boron source aqueous solution, and carrying out reduction reaction, filtration and freeze drying to obtain the high-entropy boride infrared radiation material. The method has the characteristics of simple required equipment, easy preparation method, high repeatability and high production efficiency, and can be used for industrial large-scale production. The prepared high-entropy boride material not only has a stable structure, but also has relatively high infrared emissivity, and can be used as an infrared radiation material.
