Gold Mica gaskets, Mica sheet, Mica pipe

The mica group represents 37 phyllosilicate minerals that have a layered or platy texture.
The commercially important micas are muscovite and phlogopite, which are used in a variety
of applications. Mica’s value is based on several of its unique physical properties.

The crystalline structure of mica forms layers that can be split or delaminated into thin sheets
usually causing foliation in rocks. These sheets are chemically inert, dielectric, elastic, flexible,
hydrophilic, insulating, lightweight, platy, reflective, refractive, resilient, and range in opacity
from transparent to opaque. Mica is stable when exposed to electricity, light, moisture, and
extreme temperatures. It has superior electrical properties as an insulator and as a dielectric,
and can support an electrostatic field while dissipating minimal energy in the form of heat;
it can be split very thin (0.025 to 0.125 millimeters or thinner) while maintaining its electrical
properties, has a high dielectric breakdown, is thermally stable to 500 °C, and is resistant to
corona discharge. Muscovite, the principal mica used by the electrical industry, is used in
capacitors that are ideal for high frequency and radio frequency. Phlogopite mica remains
stable at higher temperatures (to 900 °C) and is used in applications in which a combination
of high-heat stability and electrical properties is required. Muscovite and phlogopite are
used in sheet and ground forms.
