Preparation method of micro-nano-scale lamellar lithium-boron-carbon material
The invention discloses a preparation method of a micro-nano-scale lamellar lithium-boron-carbon material, which comprises the following steps: step 1, mixing lithium hydride, boron powder and nano carbon powder in an agate mortar, and grinding to obtain mixed powder; 2, the mixed powder is put into a tabletting mold and then pressed, and a raw material wafer is obtained; step 3, putting the raw material wafer into a niobium crucible, and then performing high-temperature sintering in a circulating argon atmosphere; and 4, putting the niobium crucible into a glove box, and opening the glove box to obtain the lamellar lithium-boron-carbon material. According to the invention, lithium hydride, boron powder and nano carbon powder are subjected to grinding, pressing and high-temperature sintering in sequence to obtain the micro-nano lamellar lithium-boron-carbon material, the transverse size of the lamellar layer is 200nm-2 microns, the obtained micro-nano lamellar lithium-boron-carbon material is controllable in morphology and adjustable in size, the reaction rate is increased, the crystallinity and structural stability of the material are enhanced, and the preparation method is simple and convenient. Therefore, the superconductivity of the LiBC material is favorably explored.
