Tourmaline powder is the powder obtained by mechanical crushing after removing impurities from the original tourmaline
ore.After processing and purification tourmaline powder has higher negative ion production and far infrared emissivity.
Tourmaline is also called tormaline.Tourmaline chemical formula is NaR3Al6Si6O18BO33(OH,F)4. The crystal belongs to
a group of ring structure silicate minerals of trigonal crystal system.Where R represents the metal cation, and when R is
Fe2+, the black crystal tourmaline is formed.Tourmaline crystal is nearly triangular columnar, crystal shape at both ends is different, cylindrical with longitudinal, often columnar, needle, radial and block aggregate.Glass luster, broken rosin luster,
translucent to transparent.No cleavage.Mohs hardness 7-7.5, specific gravity 2.98-3.20.There are piezoelectric and
thermoelectric properties. ElementSiO2Al2O3MgOCaOK2OFeONaO2Cr2O3TiO2%373081.20.088.11.20.220.44
