摘要

The mica group represents 34 different phyllosilicate minerals that exhibit a layered or platy structure. Muscovite and phlogopite are the commercially important mica minerals. Muscovite is the principal mica used. It is more abundant than phlogopite, has white color and superior electrical properties. Phlogopite is more temperature stable. It is used in applications where a combination of high heat stability and electrical properties is required. Mica's uses are divided into scrap and flake, and sheet. The United States consumes about 118 kt/a (130,000 stpy) of scrap and flake mica. Scrap and flake sells for between 180 dollars and 800 dollars/t (163 dollars and 725 dollars/st).
