Tourmaline powder is a finely ground substance derived from tourmaline, a complex borosilicate mineral renowned for its diverse chemical composition and remarkable physical properties. The general chemical formula of tourmaline is NaR3​Al6​(Si6​O18​)(BO3​)3​(OH,F)4​, where R can be various metal ions like iron, magnesium, lithium, or manganese, which endow tourmaline with a wide spectrum of colors and characteristics.

Formed under specific geological conditions, tourmaline typically originates from pegmatite dikes and high – temperature, high – pressure metamorphic environments. In pegmatites, which are coarse – grained igneous rocks, tourmaline crystals grow from hydrothermal solutions rich in boron, aluminum, silicon, and other essential elements during the late – stage crystallization of magma. Meanwhile, in metamorphic rocks, tourmaline forms as a result of chemical reactions among different minerals under intense heat and pressure, such as during mountain – building processes.

Major tourmaline – producing regions worldwide significantly contribute to the supply of tourmaline powder. Brazil stands out as a leading source, boasting vast deposits due to its extensive geological history filled with igneous and metamorphic activities. Sri Lanka also plays a crucial role, with its unique geological structure facilitating tourmaline formation. Madagascar, known for its rich mineral diversity, offers a large quantity of high – quality tourmaline. In China, Xinjiang and Yunnan are important domestic sources, where complex geological settings and active tectonic movements create favorable conditions for tourmaline ore formation.

After mining, tourmaline ore undergoes a series of processing steps to become powder. Initially, it is crushed into smaller fragments to break down the rock structure. Subsequently, through grinding and milling, the ore is further refined into fine particles. Purification processes are then carried out to eliminate impurities like other minerals, clay, and organic substances, ensuring the purity and quality of the final tourmaline powder.

Tourmaline powder has a wide range of applications. In the health and wellness industry, it is highly valued for its unique electrical and thermal properties. When in contact with the human body or certain environments, tourmaline powder can generate a weak electrical current and far – infrared rays. These properties are believed to promote blood circulation, enhance metabolism, and potentially improve overall well – being. In the cosmetics field, it is added to skincare products for its moisturizing, anti – aging, and skin – soothing effects. In the environmental sector, tourmaline powder can be used to purify water and air, as it can adsorb harmful substances . Additionally, in the construction and ceramics industries, it is incorporated into materials to improve their physical properties, such as strength and durability. Overall, tourmaline powder’s versatility makes it an important material in various modern applications.
