Whilst floor mica could sell for $300 per metric ton, Mica Sheet for specialization applications can sell for costs up to $2000 per kilogram. Mica Powder has many properties Which Make it appropriate for very special applications:
1) it could be split into thin sheets.
3) it's stable when exposed to light, electricity, moisture and extreme temperatures.
Most sheet mica is used to create digital devices. In these applications the sheets have been cut, punched, stamped and machined to precision measurements. Software include: diaphragms for oxygen breathing gear, markers dials for navigation compasses, optical filters, pyrometers, retardation plates in helium-neon lasers, missile systems elements, medical electronic equipment, optical instrumentation, radar systems, radiation sensor windows, along with calibrated capacitors.
The caliber of Muscovite Mica Sheet is affected by the presence of inclusions. These may impair splitting, reduce transparency, and reduce dielectric strength. Inclusions reduce the mica's worth and its capacity to be utilised in most programs.
