Far-infrared ceramic powder is a white powder made of a mixture of various substances. It is primarily characterized by its ability to emit more far-infrared radiation (higher infrared radiation rate) than normal objects. It is mainly used in the high-temperature zone for boiler heating, paint baking, and the heating and drying of wood and food. In the normal temperature zone, it is used in the production of various far-infrared 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 nano-titanium oxide coatings) possess catalytic oxidation properties. Under sunlight (especially ultraviolet light), they generate hydroxide ions with a negative charge, effectively removing indoor benzene, formaldehyde, sulfides, ammonia, and odor-causing substances, and also have sterilization functions.
