Summary:The invention discloses a preparation method of lithium hydride. The preparation method comprises the following steps: introducing inert gas into a reaction cavity of a vacuum tube type hydrogenation furnace, heating to 100-180 DEG C, and keeping the constant temperature for a first time; putting metal lithium into an air-blowing crucible and then feeding the metal lithium into the reaction cavity; performing cyclic operation of inert gas filling-vacuum pumping on the reaction cavity for multiple times, filling hydrogen from an air inlet hole in the bottom of the air-blowing type crucible, and blowing the hydrogen into the accommodating cavity through an air-blowing hole; under the condition of continuously filling hydrogen, heating the reaction cavity to 630-680 DEG C, and keeping the constant temperature for a second time, so that the metal lithium in the accommodating cavity is molten and reacts with the blown hydrogen; and further heating the reaction cavity to 690-720 DEG C under the condition of continu
