Backgrounds for the Industrial Use of Black Tourmaline Based on Its Crystal Structure Characteristics

Abstract

The industrial use of black tourmaline is based on the pyroelectricity, emission of far infrared radiation, adsorption of ions, release of negative air ions, and influence on biologic activity. The crystal structure of schorl was analyzed through a virtual three dimensional hard ball model and related to these properties. Explanations for the pyroelectricity, emission of far infrared radiation, adsorption of ions, and release of negative air ions are given based on the crystal structure...
