Tourmaline nano powder

Bixi, which mineral scientific name tourmaline, it is a kind of boron silicate mineral, still the most abundant mineral, its color is mainly red, yellow, blue, green, purple, brown, black and so on. 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. 1, Shape, Classification ownership, performance state The products classification of tourmaline are mainly divided into several kinds from color, structure, composition content,etc.: Color: Pink, Green, Black, White, Brown, Yellow and so on. Structure: Crystal tourmaline, columniatioin form tourmaline, tripartite form awl brilliant tourmaline, spherics tourmaline, radial tourmaline (fibrous), latent crystalloid tourmaline,etc. Ingredient: Magnesium tourmaline, Iron tourmaline, Sodium manganese, Chrome tourmaline and so on. 2, The spec. and granule of product ( picture of powder attached, Brazil and Xinjiang) The granule can produce it from 325 mesh - 32000 mesh. 3, The structure taken after be produced nanometer powder The result tested after air current and wet grinding: The electron microscope (SEM) will measure the image to enlarge by 3.6 ten thousand times: Tourmaline being globular, distributing evenly, particle identical, probably 70-100NM, if undergo the electron microscope test of transmission, part of (TEM) fibrous in shape that get some particle long to exceed 200NM. Short foot-path about about 30NM. How solve shape synchronized, must use air current rub and wet, can make a granule globular structure of product. At the same time,Reuse the polishing instrument of nanometer to further polish after making nanometer. 4, The examine of composition compared and physical characteristic It is use the atom spectrum and the electronic probe that synthesize the test that can obtain products test, such as, magnesium tourmaline, iron tourmaline, sodium manganese tourmaline, chromium tourmaline and chemical molecular formula. The chemical composition of Bixi and physical characteristic.
