Usage

Description

Kyanite is an aluminum silicate mineral with the chemical formula Al2SiO5. It has a triclinic crystal structure and exhibits good cleavage parallel to the macropinacoid. Kyanite's hardness varies depending on the crystallographic direction, ranging from 5 to 7.5. Its specific gravity is between 3.56 and 3.67, and it has a vitreous to pearly luster. The color of kyanite is commonly blue to white, but it can also be gray, green, or nearly black. It is transparent to translucent and is typically found in long-bladed crystals or columnar to fibrous structures. Kyanite is named after the Greek word for blue, reflecting the delicate blue color of the inner portions of its bladed crystals.

Uses

Used in Ceramic Industry:
