2. Description of the Related Art Tourmaline (tourmaline) is 950-97.
At 0 ° C boron is lost and melts at 1000-1100 ° C. When the ceramic is fired at 1150 ° C., it is not found in the fired material. That is, it is melted and melted in the fired base, and the base is significantly colored. As a physical characteristic, piezoelectricity (piezoelectricity) is generated by the piezoelectric effect (piezoelectricity). There is also a pyroelectric effect that generates "pyro electricity" when overheated. Note that the piezoelectric effect is also called a piezo effect, and is a phenomenon in which an ionic crystal generates electric polarization in response to a stress caused by an external force. Pyroelectricity is a phenomenon in which electric charges appear on a material surface in response to a temperature change. Say. As a chemical property, there is a property of generating a hydroxyl ion (H 3 O 2 ) in water. That is, water (2H 2 O) generally contains 10 −7 mol of H 3 O + (hydrogen ion concentration; hydronium ion) in 11
H (hydroxyl ion concentration, hydroxide ion) is ionized to 10 −7 mol, and the ion product is H 3 O + × OH
= K (constant). Therefore, 10 −7 × 10
Although −7 = 10 −14 , it is known that H 3 O 2 × H + ↑ = K exists, albeit very slightly, in the above equation. As a result of being decomposed into 2H 2 O → H 3 O 2 × H + ↑, water is surface activated, passivates metals in the water, and suppresses slime and the like (in the case of tap water, No red rust water appears). The reason is that a monomolecular film is formed on the surface of water, so that the effect is doubled as compared with the case of a small amount present. Recently, the application of tourmaline permanent electrodes has been studied, and as an application example, the generation of negative air ions has been confirmed, and the development of animal (including human) health promotion (low blood pressure, good sleep), etc., has been developed. Antibacterial products with the addition of tourmaline and silver are on the market,
All of them seem to be under development, and have not yet obtained sufficient technical evaluation.

The technical evaluation of conventional purification and reforming of water based on tourmaline as a base material has a developing relationship, but has not been highly evaluated. Regarding air, no new product development has been announced. Examination of commercially available tourmaline pellets for improving water quality and tourmaline ceramic balls for purification shows that the surface activation effect of water is significantly reduced in about 6 to 8 months in water. On the other hand, it has been known for a long time that a silver-containing compound or an impregnation causes coloring, discoloration, fading or the like by the action of oxygen or light in the air or water. Similar phenomena are observed with conventional tourmaline ceramic balls and tourmaline pellets.
