The invention discloses particulates with double functions of internal radiotherapy and thermal therapy, and a preparation method thereof. The particulates are mainly compounded and formed by glass containing radioactive species yttrium-90 or / and phosphorus-32, and solid ferrite with magnetocaloric effect. When the particulates intervene in vivo, the radioactive species yttrium-90 or / and the phosphorus-32 contained in the glass can release Beta rays in vivo to kill cancer cells intervening in surrounding tissues without damaging the distant healthy tissues; the solid ferrite has good hysteresis exothermicity and can transform exosomatic magnetic energy into heat energy so as to release heat under the action of an external alternating magnetic field, so that the temperature around the tumor area can raise to 43 to 47 DEG C within a short time, and tumour cells intervening in the surrounding tissues are burnt and killed without influencing normal cells with better heat tolerance, thereby realizing the purpose of treating tumor by combining the internal radiotherapy and the thermotherapy, and having double lethality to cancer cells. The method for combining the radiation treatment and the heat treatment is an indispensable supplementary therapy means to treat the malignant tumor with chemical drug resistance. In addition, the particulates have good chemical stability and biocompatibility, and have great application prospect in the aspect of treating the malignant tumor.
