Tourmaline is one of the very few functional minerals in nature with permanent electrodes. Unlike ordinary gemstones that are mainly valued for ornamentation, its greatest core value lies in unique physical functional properties. With stable thermoelectricity, piezoelectricity and electrode characteristics, tourmaline can continuously release air negative ions and radiate far-infrared rays. Meanwhile, it possesses excellent adsorption purification and ion exchange capabilities, making it an indispensable natural green functional material in environmental protection, health care and industrial fields, with far stronger functionality than conventional natural minerals.
The continuous release of air negative ions is the most iconic core function of tourmaline. With inherent permanent positive and negative electrodes, tourmaline can stably release high-concentration air negative ions at normal temperature and pressure without external energy supply. Its effect is long-lasting, non-decaying and side-effect-free. Known as "air vitamins", negative ions can actively adsorb suspended particulate matters such as PM2.5, dust and smoke in the air to promote their sedimentation. They can also neutralize formaldehyde, benzene, TVOC and other harmful decoration gases, decompose peculiar smells, mildew and lampblack odors, effectively purify air in indoor and enclosed spaces, improve air quality and relieve discomfort caused by air pollution.

Efficient far-infrared radiation is another vital core function of tourmaline. At room temperature, tourmaline steadily emits far-infrared waves ranging from 4 to 14 micrometers. Known as "life light waves" in the scientific community, this wavelength is highly consistent with the infrared radiation wavelength of the human body. The light waves can penetrate the surface of human skin and reach subcutaneous tissues, effectively boosting blood circulation and metabolism, activating body cells, improving human microcirculation and alleviating physical fatigue. Based on this function, tourmaline is widely applied in health-care home textiles, physical therapy equipment and wearable protective gears, serving as a natural raw material for health preservation.
Tourmaline also has powerful functions of water purification and water activation. Its unique electrode structure enables ion exchange and electrostatic adsorption, which can effectively adsorb heavy metal ions, impurities, suspended solids and bacterial microorganisms in water, filter and purify sewage and tap water, and reduce water pollutant content. In addition, tourmaline can adjust the pH value of water, convert ordinary water into weakly alkaline small-molecule water, enhance water activity, and improve water taste and quality. It is widely used in water purification filter elements, aquatic purification, industrial wastewater treatment and farmland water improvement scenarios.
Furthermore, tourmaline delivers excellent static dust prevention, antibacterial and auxiliary electromagnetic shielding functions. The weak electrostatic field generated by its electrodes can adsorb dust on object surfaces to achieve long-term dust prevention and cleaning. It can also destroy the living environment of bacteria and molds, inhibit microbial growth, and achieve antibacterial and mildew-proof effects. In industrial applications, modified tourmaline can assist in weakening low-frequency electromagnetic radiation, meeting the protection needs of electronic equipment and home building materials. Meanwhile, tourmaline features stable properties, high temperature resistance, corrosion resistance, no radioactivity, safety and environmental friendliness, and can be recycled for long-term use.

Benefiting from its multiple natural composite functions, tourmaline has been widely applied on a large scale. In the civil field, it is used in environmental coatings, purification filters, health-care bedding and water purification equipment. In the ecological field, it is applied to soil improvement, water restoration and air governance. In the industrial field, it serves as functional new materials, precision equipment protection and environmental auxiliary materials. As a multi-functional natural mineral integrating purification, health care, environmental protection and modification, tourmaline boasts the core advantages of energy-free operation, green safety and long-term stability. It has become a core functional raw material for modern green industries and health industries, with extremely broad application prospects.
