Mica

Mica is invaluable in the electrical and electronics industries because of its unique combination of physical, chemical and thermal properties, low power loss factor, dielectric constant and dielectric strength. Also used in insulation, paint, metalurgical, and polymers. Mica flake is used in low fire clay bodies to add a sparkle effect.

Phlogopite

Micas have a layer charge of about 1.0 per half-cell formula unit and are both dioctahedral, e.g., muscovite and paragonite, and trioctahedral, e.g., biotite, phlogopite, and lepidolite (Table 2.4). With the exception of paragonite, a Na-bearing mica, the other micas have K + in the interlayer positions to satisfy the negative charge resulting ...

Phlogopite Mica | SPI Supplies

The mica mineral phlogopite, when it is cleaved, results in a rougher surface. The mineral also lacks the high optical clarify of muscovite, at least when talking about grades V-4 or better.
