Far infrared powder is a white powder made from a mixture of various substances. It is primarily characterized by its ability to emit more far infrared rays (higher infrared radiation rate) than normal objects. In high-temperature areas, it is mainly used for boiler heating, paint baking, wood and food heating and drying, etc. 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 nano-titanium oxide coatings) have a catalytic oxidation function, generating negative one-valent hydroxide ions under sunlight (especially UV light), and possess bactericidal properties.
