Abstract
Tourmaline is a kind of non-metal mineral, which has been applied widely in environmental protection, such as radiating infrared, producing ion negative and shielding electromagnetic radiation. It is proved that tourmaline has the properties of spontaneous electrode effect and weak magnetism. Tourmaline from different areas has some differences on internal crystal structure and chemical composition. This paper studied on the infrared radiation properties of four different kinds of tourmaline produced in Hebei Guangxi, Henan, Xinjiang. Our experiments indicated that different species of tourmaline has different rate of infrared radiation on the same condition, and infrared radiation rate changes with temperature and particle size.
