The quality of black tourmaline is best in China, at also is rare in the world, and the ore of tourmaline contain to measure 99% above, specific weight 2.98--3.20, degree of hardness 7-7.5, chemistry composition complicacy, chemistry type is: NaR3Al6[Si6O18][BO3]3(OH,F)4, contain the iron to measure many for black, contain the li, Mn, Cs tomeasure many for the rose or navy blue, contain the mg to measure many for brown or yellow, contain the cr to measure many for deep green, glass iuster, translucent to transparent, the color and iuster is transparent can be used as the precious stone, and call BIXI in China, because of the hot electricity for having of this kind of mineral but call the tourmaline. The tourmaline S traditional use is mainly as below:
Electronics industry, voice electricity material, electromagnetic wave protection instrument, grind the material, porcelain, standard the instrument with the industry dollar on the quipments piece, national defense, aviation, cigarette, car, toothpaste, marine products, keep the flower, air condition, medical treatment the health care, food, cosmetics, coating, and varnish, spin and weave, make the shoe industry, jewelry, cellular phone to hang an etc. Profession.
The single crystal tourmaline in Xinjiang can produce negative leave the son, and shoot the far infrared ray, and absorb the electromagnetic wave, conduct electricity anti-electrostatic.

The advantage of tourmaline is not alone function , it will develop the compound function, the result is various , underneath , we gives examples to elaborate explain ,how can make the water of health and good flavor .
The member of water can't alone exist, it will combine with hydrogen, formation member group. the water of activate is 5-6 member group.Under this circumstance, the activity of member is most prosperous ,
If the water have the impurity things or heavy metals, these impurities thing will enter the member group of water, becoming the several tens member group, repressing the activity of the member of water, make water change difficult to drink, and the permeate ability of cell will lower also, Because of the chlorine processing and the size of member group, when the running water change difficult drinking .
The member group of the running water have 12-16 ,generally, being subjected to the polluting water is about 35-36 , the member group of the running water could not change when it pass the instrument of Processing water .it will become 5-6 ideal members if make use of tourmaline of 4-14 micron electromagnetic wave to processing water of higher member group, The tourmaline output electromagnetic wave ,it can raise the physiology activity of the human body ,and can make water activate also.
How size of member group ,it use the oxygen nuclear magnetic resonance equip measurement ,the water of tourmaline handled, the flavor is very good, permeating strong, can raise absorption ability of the stomach, because of the member group contract, so , only drink it,you will feel the function of the tourmaline.
Moreover, specially reminding it have the five greatest condition to make the tourmaline exertive the biggest result ( Convection, Difference temperature , Pressure, Humidity, Rub), the operation method of the mistake will result the contrary result
