Tourmaline
Tourmaline Powder is one kind of silicate substance with aluminium, natrium, magnesium and lithium ring structure being of containing boron. It is of thermoelectricity and piexoelectricity. Due to the electric self-polarization of tourmaline, polarized energy comes from the change of temperature, the heat releasing coefficient is 10-74×10-6c.cm-2k-1. When the temperature and pressure changes (including micro change), then will cause potential difference (voltage). This kind of static voltage is up to 1 million electron volts and will accelerate surrounding air occur ionization. The electrons being shot down adhere close water and oxygen molecule, and make them transform into air negative ions (namely H3O2- and O32-), and make polarity ions in balance position oscillate, so that causes dipole square change to generate negative ions.
