The invention relates to a silicon nitride gradient porous capillary core for a loop heat pipe and a preparation method of the silicon nitride gradient porous capillary core. The preparation method comprises the following steps: injecting at least two types of silicon nitride slurry having different proportions into a mold for gel solidification, drying, sintering and processing to obtain the silicon nitride gradient porous capillary core for the loop heat pipe, wherein the silicon nitride slurry is prepared from silicon nitride powder, a sintering aid, gel, a pore forming material and water;the content of the pore forming material in the silicon nitride slurry injected into the mold at first is lower than that of the pore forming material in the silicon nitride slurry injected into the mold later.
