Tourmaline that belongs to the hexagonal system having electrical features is widely used as a multi-functional ore from high emission of far

infrared rays and II-Ray action to the emission of anions, but, as it is very weak to heat, in case of ceramic balls formed at the firing temperature of

650 degrees sim;700 degrees

it is hard to expect the original functions, and, even in case of applying tourmaline with the heat of fewer than 700 degrees by flit processing,

there have been many difficulties in use due to continuing particulates. However, through constant research and development, we have completed

tourmaline balls by the temperature of fewer than 230 degrees with a mixture of pure tourmaline powder (325 Mesh) with functional ores,

using a new processing method, and as the result, we have made the functions maximized.

Many other ceramic balls are available: - activated carbon ball, - dechlorinated balls, - sterilization balls, - string alkali balls, and - reduction catalysts
