Abstract

The invention relates to an artificially synthesized crystal, and in particular relates to an artificially synthesized tourmaline crystal and a preparation method thereof. The tourmaline provided by the invention is a crystal nano particle which is prepared by treating a mineral substance in an acidic solvent with a hydrothermal synthesis method, wherein the weight part ratio of the mineral substance to the acidic solvent is (1-15):1; the mineral substance is a mixture of at least two of clay, medical stone, zeolite, serpentine or gneiss; and the acidic solvent is one or more than one of hydrofluoric acid, sulfuric acid or perchloric acid. According to the preparation method provided by the invention, the tourmaline is prepared by using a common and productive mineral substance and the acidic solvent without adding any natural tourmaline, thus material selection is convenient, and cost is low; the artificially synthesized tourmaline prepared by the method in the invention can sustainably release negative ions, has the same, even better effect as compared with the natural tourmaline, can be widely applied to various industrial fields and has good effect.

Description

technical field [0001] The invention relates to an artificially synthesized crystal, in particular to an artificially synthesized tourmaline crystal and a preparation method thereof. Background technique [0002] Tourmaline is also called tourmaline or tourmaline. Its chemical composition is relatively complex. It is a silicate rock mineral mainly containing boron and also containing aluminum, sodium, iron, magnesium, lithium and other elements. Tourmaline was first discovered in Sri Lanka when it was noticed that the gemstone would become electrically charged when heated, a phenomenon known as the pyroelectric effect. Tourmaline can permanently generate micro-current, which is similar to the current of human nerves, so that it can promote blood circulation and smooth effect. In addition, tourmaline can also release negative ions, which have the ability to adjust the ion balance of the human body and activate Cells can relax the body and mind, improve the self-healing rate,...
