Far-infrared ceramic powder is a white powder composed of various substances. Its primary feature is its ability to emit more far-infrared radiation (higher infrared emissivity) than ordinary objects. It is mainly used in high-temperature areas for boiler heating, paint baking, and heating and drying of wood and food. In normal temperature areas, it is primarily used in the production of various far-infrared thermal insulation materials, such as far-infrared ceramic powder, far-infrared ceramic fiber, far-infrared ceramic polyester, and functional ceramic materials with far-infrared properties. Far-infrared ceramic coatings (including nanoscale titanium dioxide coatings) possess catalytic oxidation capabilities. Under sunlight exposure (especially UV light), they generate negative hydroxide ions, effectively removing indoor benzene, formaldehyde, sulfides, ammonia, and odor-causing substances, and also have sterilization properties.
