Tourmaline also known as tomalin, tourmaline, tallow gold, electrically charged stone.TOURMALINE is a borosilicate mineral with a general chemical formula of NaR3Al6[Si6O18][BO3]3(OH,F)4. TOURMALINE is a boron-bearing silicate mineral with a circular structure of aluminum, iron, sodium, magnesium and lithium, with a mohs hardness of 7-7.5 and specific gravity of 2.98-3.20.
Tourmaline was first found in Sri Lanka and was considered to be as precious as diamonds and rubies.It has been noted that this gem carries an electric charge when heated, a phenomenon known as the pyroelectric effect, hence the name tourmaline.
2.Application of tourmaline:
Tourmaline is widely used in environmental protection, electronics, medicine, chemical industry, light industry, building materials, etc.It has become a new type of industrial mineral with high added value and has been widely valued.
Application of single tourmaline material: activating water, neutralizing acid and alkali in water, absorbing heavy metal ions, purifying air
Application of tourmaline in the field of composite materials:
Photocatalysis: by using the electric field on the surface of tourmaline and the far infrared ray emitted, photogenerated electrons can be captured by the anode of tourmaline, so as to improve the utilization rate of photogenerated holes and the efficiency of photocatalysis.
Electromagnetic shielding: the material containing tourmaline powder into a variety of electronic components and equipment shell, can effectively play the role of electromagnetic shielding.
Building coating: tourmaline is added in coating, not only can increase the number of anion in air, still can eliminate the peculiar smell that coating place sends out, be beneficial to human body health.
Functional ceramics: tourmaline is added to the traditional ceramic body to enhance the function of ceramics.
Textile fiber: the textile clothing with tourmite powder can promote the blood circulation and metabolism of human body more than the textile clothing with a single function. It is an ideal material for health care.
Cosmetics: domestic and foreign use tourmaline has far infrared emission, the release of negative ions and bioelectricity and other characteristics have been developed bleeding tourmaline additives more cosmetics.
