Widely used in environmental protection, electronics, daily use chemicals, textiles, ceramics, buildings, drinking water activation, sewage treatment, air purification, healthcare products etc.
Because Tourmaline has piezoelectricity , thermoelectricity and other unique physical & chemical properties,it can release electromagnetic radiation of far-infrared band.The electromagnetic radiation can provide negative oxygen ions which has antibiosis, deodorization and other functions.
