Summary:The invention relates to gadolinium borate and a preparation method and application thereof. According to preparation of gadolinium borate, Gd<3+> is used as a raw material, and small molecular weight BO3<3-> is used as a ligand. The preparation method comprises the following steps: placing gadolinium oxide and boric acid into a quartz porcelain boat, grinding solids into powders, uniformly mixing, drying, transferring the quartz porcelain boat into a quartz tube furnace, heating to 400 DEG C and keeping the temperature for 10 h, heating to 1000 DEG C and keeping the temperature for 6h, cooling to room temperature to obtain a white powdery solid, washing and carrying out suction filtration, and drying to obtain gadolinium borate. The gadolinium borate which is white powdery crystal can be applied in preparation of magnetic refrigeration materials. Synthetic equipment is simple, and the preparation method is fast and easy to operate. The gadolinium borate is a borate compound and has very strong stability and
