Introduction of Tourmaline Tourmaline is] after the tourmaline ore to remove impurities, after mechanical comminution of the obtained powder. After processing purified tourmaline powder has a high amount of negative ions and far-infrared emission rate. Tourmaline, also known as tourmaline. Tourmaline (tourmaline) chemical formula is NaR3Al6Si6O18BO33 (OH, F) 4, crystal trigonal system of a family of cyclic structure silicate minerals in general. Wherein R represents a metal cation, when R is Fe2 +, the constitution black tourmaline crystals. Tourmaline crystal was nearly triangular columnar crystal form different ends column mask vertical stripes, often columnar, needle, radial and massive aggregates. Glass luster, fracture rosin luster, translucent to transparent. No cleavage. Mohs hardness 7-7.5, specific gravity 2.98-3.20. Piezoelectric and pyroelectric properties. The main components of tourmaline tourmaline] also called tourmaline. Tourmaline occurs in our country is to get the Emperor Zheng Xi AD 644, called "tourmaline" Tourmaline complex chemistry, is a kind of boron-based, also containing aluminum, sodium, iron, silicate rock-forming minerals magnesium, lithium and other elements. Tourmaline was first discovered in Sri Lanka, it was noted that this gem will take charge when heated, a phenomenon known as the pyroelectric effect, so named Tourmaline.
