Mica flakes is used principally in the electronic and electrical
industries. Its usefulness in these applications is derived from
its unique electrical and thermal insulating properties and its
mechanical properties, which allow it to be cut, punched, stamped,
and machined to close tolerances. The leading use of block mica is
as an electrical insulator in electronic equipment. High-quality
block mica is processed to line the gauge glasses of high-pressure
steam boilers because of its flexibility, transparency, and
resistance to heat and chemical attack. Only high-quality muscovite
film mica, which is variously called India ruby mica or ruby
muscovite mica, is used as a dielectric in capacitors. The highest
quality mica film is used to manufacture capacitors for calibration
standards. The next lower grade is used in transmitting capacitors.
Receiving capacitors use a slightly lower grade of high-quality
muscovite.
Mica sheets are used to provide structure for heating wire (such as in Kanthal or Nichrome) in heating elements and can withstand up to **0 °C (1,**0 °F).
