Usage

Description

Tourmaline is a group of complex cyclosilicates containing boron, with the general formula NaR3 2+Al6B3Si6O27(H,F)4, where R = Fe2+, Mg, or (Al + Li). It is a semi-precious stone known for its trigonal, elongated crystals and variable colors, often with different colors at each end. Tourmaline is used as a gemstone and, due to its double refraction and piezoelectric properties, is also utilized in polarizers and some pressure gauges.

Uses

Used in Gemstone Industry:
Tourmaline is used as a gemstone for its aesthetic appeal and unique color variations.
Used in Scientific Instruments:
Tourmaline is used as a component in polarizers and some pressure gauges due to its double refraction and piezoelectric properties.
Used in Agriculture:
Tourmaline, being a borosilicate, serves as the main source of boron found in soil. It is a mixture of silicates and borates from which boron is extracted, contributing to the health and productivity of the soil.
Used in Industrial Applications:
Tourmaline is used to increase product viscosity in various industrial applications.
Note: There is little clinical evidence supporting therapeutic claims associated with tourmaline.
