Far Infrared Radiation Property of Rare Earth Mineral Composite Materials

Rare earth mineral composite materials were prepared using rare earths and natural far-infrared mineral materials. The influences of rare earth additive content and heat treatment temperature on the far infrared radiance were studied. The results show that the far infrared radiance of rare earth mineral composite materials is 0.93 when the rare earth additive content is 6% and heat treatment temperature is 750 °C.
