In the industrial electronics field, tourmaline powder serves as a core raw material for precision component manufacturing. Relying on its stable piezoelectric effect, it can be made into high-sensitivity tourmaline pressure gauges, sonar elements and wavelength regulators, which are used to detect tiny physical disturbances, support submarine depth measurement and ensure stable operation of military precision equipment. It is also an ideal material for electromagnetic shielding protection: when added to composite materials, it can neutralize radiation cations around electronic devices, effectively reduce electromagnetic interference, and is widely embedded in electronic equipment shells, automotive cab protective layers and high-frequency circuit shielding structures to protect equipment operation safety and human health.

For environmental protection and building materials industries, tourmaline powder brings dual values of water purification and air improvement. In water treatment, it can efficiently adsorb heavy metals, suspended impurities and residual chlorine in water, activate water molecules to make them closer to weakly alkaline healthy water, and is a standard functional filler for water purifier filter elements, hydrogen water bottles and industrial sewage treatment systems. In indoor air treatment, tourmaline powder can be added to interior wall coatings, wallpapers, ceramic tiles and ceiling materials. The negative ions it continuously releases can effectively decompose formaldehyde, remove peculiar smells from paint, tobacco and daily life, inhibit bacterial growth, and create a long-term fresh indoor air environment for homes, offices and commercial spaces.

In daily health and textile sectors, tourmaline powder shows outstanding application potential. Ultra-fine tourmaline powder with 15000 mesh fineness can be added to cosmetics and personal care products: it helps adjust product viscosity, promotes skin microcirculation through mild far-infrared effect, assists skin to absorb nutrients, and is widely used in facial cleansers, skin creams, masks and shampoo formulas. When processed into functional fibers, tourmaline powder can be made into anti-electromagnetic radiation shirts, warm bedding, health care insoles and anti-mold moisture-proof textiles, bringing comfortable health experience to users. It is also a common core material for heating patches, warm stickers and tourmaline sweat room building materials, which can release stable far-infrared rays when heated, helping relieve body fatigue.

In agricultural and other extended scenarios, tourmaline powder also plays an irreplaceable role. It can be added into soil conditioners to adjust soil pH value, improve soil air permeability and water retention capacity, release trace elements beneficial to plant growth, and promote crop development. With Mohs hardness up to 7-7.5, it can be used as a high-performance hard abrasive material for precision polishing processes. In recent years, it has also been widely used in pet health products, fresh-keeping packaging materials for fruits and vegetables, and deodorant additives, showing extremely rich application expansion space.
