Far infrared powder is a white powder composed of various substances. Its primary feature and function are its ability to emit more far infrared rays (higher infrared radiation rate) than ordinary objects. It is mainly used in the high-temperature area for boiler heating, paint baking, and the heating and drying of wood and food. In the normal temperature range, 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 ceramics with far infrared properties. Far infrared ceramic coatings (including titanium dioxide coatings) have a catalytic oxidation function, generating negatively charged hydroxide ions in sunlight (especially UV light), and possess bactericidal properties.
