In China, the term “Bixi†appeared very early in the Qing Dynasty. It is one of the materials used by the top and second-class officials, and is also used to make the beads they wear. At the same time, the tourmaline is also one of the favorite of Empress Dowager Cixi. Therefore, in the Empress Dowager Cixi, the tourmaline received unprecedented attention in China. Among the funerary objects of the Empress Dowager Cixi of the Qing Dynasty, there was a lotus flower made of tourmaline, weighing 36 and 8 yuan, and a pillow made of watermelon tourmaline, which was worth 750,000 two silver. Many people should know that the mineralogy of the colored gemstones that many women like is called tourmaline. Some sellers in the mall may also call it the electrical name directly, but the name of the tourmaline is familiar to everyone. The reason why it is called tourmaline is because this ore will generate electricity by itself. How does it produce electricity? Will it hurt people's bodies? Tourmaline is the only ore that produces electricity in minerals. It is charged when heated. This phenomenon is called pyroelectric effect. The secret of this characteristic of tourmaline is the shape of crystal. The crystal of tourmaline has a columnar shape, and the three faces at both ends are combined at an angle of one hundred and twenty degrees. The upper angle is one hundred and twenty degrees, and the lower angle is one hundred and eighty degrees. This shape was originally impossible to produce electrical. However, in the tourmaline crystals, the positrons and negative electrons are arranged in an orderly manner. After heating, the electrons reach the two poles of the crystal, and positive and negative charges are generated. This phenomenon is called coke. In addition, the electrons are transmitted to the two poles respectively, and when subjected to pressure or tension, positive and negative charges are generated, which is called piezoelectric phenomenon. Tourmaline produces electricity by the two methods described above. The pressure of the tourmaline in the vertical and horizontal directions will be polarized and produce electricity. Therefore, if the voltage is to be processed, the tourmaline is a good mineral. The tourmaline in heating will generate electricity when cooled. A voltage is also generated when the pressure is weakened, when the original state is restored, or when the tension is applied to the opposite. Adding an energy, but getting a double result, that is, the great advantage of the tourmaline. Therefore, the name of Tourmaline "tourmaline" came from this, but its power is weak and has no effect on the human body.
