Technical Field

Background
Functional ceramics are materials which mainly utilize the non-mechanical properties of the materials in application, and the materials generally have one or more functions such as electricity, magnetism, light, heat, chemistry, biology and the like, and coupling functions such as piezoelectricity, piezomagnetism, thermoelectricity, electrooptical, acousto-optic, magneto-optic and the like. With the rapid development of material science, various new properties and new applications of functional ceramic materials are continuously recognized and actively developed. Due to the high development of science and technology, the requirements on the performance and quality of ceramic materials are higher and higher, and partial ceramics are promoted to develop into novel materials with special function types. Such ceramics, both in terms of performance and use and in terms of manufacturing process, require a high degree of definition, so that together with structural ceramics they are collectively referred to as fine ceramics (new ceramics).
The infrared radiation ceramic not only can disinfect and resist bacteria, but also has the application functions of promoting metabolism, activating organisms, improving immunity and the like. The principle of the preparation of the infrared radiation functional ceramic product is that the infrared radiation powder is required to be selected to have high performance, the infrared radiation powder directly absorbs heat emitted by the surrounding environment and converts the heat to output far infrared energy, and the principle is that the change of the molecular dipole moment of the material and the oscillating electric field of light generate an interaction result. In the oscillation process, the multi-ion system changes the symmetry property of the molecule, so that the dipole moment is changed, and the infrared absorption capacity and the infrared emission capacity can be improved to a greater extent.
