What’s the difference between Tourmaline Powder and Negative Ion Powder?
Tourmaline Powder and Negative Ion Powder are two different types of products. (Of course they have some common parts) Tourmaline Powder is one kind of powder made of tourmaline as main raw materials through grinding. In generally it can be used for products related with water (such as Tourmaline Ceramic Ball), directly contact human body (such as cosmetics, etc.) But Negative Ion Powder contains little Tourmaline Powder (Tourmaline Powder is not the main materials), it also contains other nano materials (such as silicon oxide, alumina and rare earth, etc.) to cooperate for processing and grinding. It is mainly used for ornaments, necklace, sports sleeve guards, paints and textiles, etc.
