Embodiment 1

[0017] Use 325 mesh tourmaline powder and LiCl-CaCl 2 (LiCl accounts for 20% to 40% by weight, CaCl 2 60% to 80% by weight) or LiCl-KCl (30% to 50% by weight of LiCl, 50% to 70% by weight of KCl) binary solid solution phase mixed at a weight ratio of 1:1 Evenly; put it into a crucible resistance furnace, heat to 500-800°C, keep it warm for 4 hours, cool, wash, and dry to obtain a red Li with a lightness value L* of 28-38 and a "reddening" degree a* value of 5-14. -tourmaline.

Embodiment 2

[0019] Use 325 mesh tourmaline powder and LiCl-CaCl 2 (LiCl accounts for 20% to 40% by weight, CaCl 2 60% to 80% by weight) or LiCl-KCl (30% to 50% by weight of LiCl, 50% to 70% by weight of KCl) binary solid solution phases are mixed evenly at a weight ratio of 1:1 Put it into a crucible resistance furnace, heat it to 500-750°C, keep it warm for 8 hours, cool, wash, and dry to obtain a red Li- tourmaline.

Embodiment 3

[0021] Use 325 mesh tourmaline powder and LiCl-CaCl 2 (LiCl accounts for 20% to 40% by weight, CaCl 2 60% to 80% by weight) or LiCl-KCl (30% to 50% by weight of LiCl, 50% to 70% by weight of KCl) binary solid solution phases are mixed in a weight ratio of 1:1 Uniform; put it into a crucible resistance furnace, heat to 500-700°C, keep warm for 24 hours, cool, wash, and dry to obtain a red Li with a lightness value L* of 29-38 and a "reddening" degree a* value of 4-12 -tourmaline.

Abstract

The invention relates to a method used for changing surfaces of black tourmaline powder into red. According to the method comprises following steps: tourmaline powder is mixed with a binary solid solution containing LiCl; an obtained mixture is heated to 500 to 800 DEG C in a molten salt method reaction vessel, and is reacted for a certain period of time; and obtained FeCl3 and the LiCl binary solid solution residual are cooled, washed with clean water, filtered and dried so as to obtain the tourmaline powder with red surfaces. The method comprises steps of mixing, performing of molten salt method, washing, filtering, and drying. The method is capable of changing the surfaces of black tourmaline powder into red effectively.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a method for changing the surface of black tourmaline powder to red. Background technique [0002] Tourmaline is a relatively common borosilicate mineral. There are abundant reserves in our country. Black tourmaline is limited in scope of application because of its black color. Most tourmalines in nature are black, and only a few tourmalines are colored. Among them, red tourmaline has the highest value, and black tourmaline has the lowest value. Therefore, a method has been developed to convert black tourmaline into black tourmaline. Changing the color to red tourmaline has a lot of room for appreciation. [0003] The chemical formula of tourmaline is XY 3 Z 6 Si 6 o 18 (BO 3 ) 3 W 4 , Tourmaline structure belongs to the trigonal crystal system. Among them, X represents a large cation, mainly composed of K, Ca, Na and other elements. Crystal structure characteristics: The cry...
