Description

technical field [0001] The invention relates to a supergravity hydrothermal reaction equipment, which has the advantages of both supergravity and hydrothermal reaction, and is suitable for preparing various materials with special functions and structures. Background technique [0002] Hydrothermal [1-5] It is one of the methods for one-step preparation of nanomaterials. Many high-temperature phase nanomaterials can be directly prepared by this method without sintering. The nano-powder prepared by the hydrothermal method is carried out in an unforced state, and the formed powder has the characteristics of complete grain crystallization and good dispersibility. Therefore, it is difficult to obtain various non-equilibrium phase substances by this method. [0003] Supergravity is a force that is much greater than gravity when an object rotates centrifugally around an axis, that is, when a material rotating around an axis rotates at a certain speed, when the rotational speed r...
