Description

technical field [0001] The invention relates to a nano-scale far-infrared ceramic powder, in particular to a preparation method of a high-efficiency infrared ceramic powder, and belongs to the field of functional material manufacturing. Background technique [0002] Far-infrared ceramic powder is made of inorganic minerals, non-metal oxides and metal oxides. The essence of the development of infrared radiation technology is to obtain sufficient intensity of infrared radiation. The core is to develop materials with high emissivity. The infrared radiation of materials It is produced by the change of dipole moment caused by the vibration of its particles. According to the vibration symmetry selection rule: the lower the symmetry of the particle vibration, the greater the change of the dipole moment, and the stronger its infrared radiation. Since ceramic materials are substances with a macromolecular structure composed of polyatoms, polyatoms are easy to change the symmetry of ...
