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 the heating and drying of wood and food. In normal temperature areas, it is used to produce various far-infrared thermal insulation materials, such as far-infrared ceramic powder, ceramic fiber, ceramic polyester, and functional ceramic materials. Far-infrared ceramic coatings (including nano-titanium oxide coatings) have a catalytic oxidation function. Under sunlight (especially UV light), they generate negative hydroxide ions, effectively removing indoor benzene, formaldehyde, sulfides, ammonia, and odor-causing substances, and possess bactericidal properties.
