Bixi Instruction
The BIXI, which mineral name tourmaline, it contains the most abundant color comparing with all other gems .Its color has various ones, such as, red , yellow , blue , green , purple , brown , black and excessive between two kinds of colors, for instance pink, the more special one is often many kinds of colors on the same kind of crystal, called the multicolor tourmaline.
The Bixi’s chemical formula is very complex which be written as (Na , Ca) (Mg , Fe2 +, Fe3+,Li,Al)3AL6[Si6O18](Bo3)3(OH; F)4. Its crystal belongs to the three sides crystal which mostly show short column , long column or needle column form , the both end has different conical surfaces, section take the form of spherical trigonometry, crystal except that black, colourless and opaque , generally can see dichroism obviously. The cylinder is long usually including much more element Fe and Mg, taking the form of tripartite column with element Mg, the crystal is crassitude; The lithium tourmaline often takes the form of needle.
The producing area of Bixi is mainly, Brazil , U.S.A. , Burma , Sri Lanka , China (Xinjiang , the Inner Mongol , Yunnan ). Now there are pink tourmaline, Verdelite, Brown tourmaline, Rubelite, Yellow tourmaline, Schor., appearing in the market commonly.
The chemical composition of tourmaline and physical characteristic
Name Chemical composition Proportion Refraction rate Color
Lithium tourmaline Na Al，Li 3.03-3.10 1.615-1.655 Pink, Red, Blue, Yellow, achromatism.
Calcium lithium tourmaline Ca Al，Li 3.02 1.637-1.621
The following two different producing area of tourmaline have also different structure:
Xinjiang area: The tourmaline is mainly the pegmatite of crystal hole, mainly existence with lepidolite , emerald , crystal , topaz , purple apatite , yellowish green spodumene , aquamarine ,etc.
Brazil: The tourmaline is mainly a placer , mainly existence with yellow gem , amethyst , diamond.
Anion and infrared contrast
Name (original) Negative ion Infrared
Xinjiang tourmaline 2620 pc/ c.c. 85%
Brazil tourmaline 3850 pc/c.c. 88%
Processing: Processing apparatus generally combine airflow grinding machine with muller, if simple one apparatus is very difficult to accomplish nanometer, if want to get ideal nanometer particle, there must be the following procedure : break up products –airstream crush- grind wetly- drying- airstream crush again - sealed packaging ( Apparatus : QT-6A crusher, QLM5A40 air current grind, SG-1SPNM grinding machine )
Granularity : According to the application of different lines, in granularity, such as, in health care the granularity is 325 mesh - 1250 mesh , 2000-5000 mesh in paint industry, 12500mesh-25000mesh in textile industry, etc. At the same time, we can also process specially among other trades according to the request of customer.
Mainly application industries: Commonly apply in Hi-Tech fields such as textile , cosmetics , Paint, medical equipment, medicine, health product, underwear, bedding, gasoline economizer , electric splint , pottery ,etc.
