description	The invention relates to a preparation method of LaB6 powder and a sintered body thereof, which comprises the following steps: (1) weighing reaction materials according to a preset proportion, and adding a preset content of inert diluent to prepare an initial mixture; (2) uniformly mixing the initial mixture in a ball mill, and then pressing into a cake-shaped blank with the diameter of 80 mm and the height of about 40 mm on a press machine; (3) putting the cake-shaped blank into a reaction kettle, putting an ignition agent on a blank body, filling protective gas for gas washing, filling the protective gas for pressure maintaining, and continuously heating until a self-propagating reaction occurs in a system, so as to obtain a blocky initial product; (4) crushing the primary product, leaching with a hydrochloric acid solution and distilled water, and drying in a vacuum drying oven after reaching the purification standard to obtain LaB6 powder; and (5) the prepared LaB6 powder is put into a high-strength graph
