Synthetic mica (fluorphlogopite) is an artificially produced mineral with properties significantly superior to natural mica, in particular:
- highly chemical stability (even in contact with concentrated hydrochloric or sulfuric acid)
- excellent transmittance from UV to IR,
- outgasing-free at high temperature in vacuum,
- excellent electrical insulation,
- high heat endurance (from -100 °C up to 1100 °C),
- non-radioactive background,
- insensitive to the conditions for long-term storage
Fluorflogopite is particularly appreciated for high temperature resistance, corrosion resistance and light transmission, which are incomparably better than in other types of mica. Synthetic mica can work at 1100 ℃ for a long time without reaction with strong acid and alkali. In addition, it has excellent light transmittance (completely transparent).
Our offer for synthetic mica includes:
- ground synthetic mica
- synthetic mica flakes,
- synthetic mica in form of discs and rectangular plates.
We offer synthetic mica (fluorphlogopite) in the ground and in the form of flakes. Depending on the size of the particles, you may have a fine powder (with the consistency of flour) or fine flakes (about 0.5 mm). Synthetic ground mica is very white (see section Comparison between synthetic and natural mica)and retains all the properties of synthetic mica, ie high temperature resistance, no reaction to UV radiation and weather conditions, resistance to aggressive chemical substances.
We offer synthetic ground mica in standard granulation:

We offer rectangular synthetic mica (fluorphopopite) plates with the following dimensions:
- minimum: 8 mm x 8 mm,
- maximum: 165 mm x 53 mm,
and fluorphlogopite discs with diameters Φ from 5 mm to 75 mm.
Typical thickness of synthetic mica plates and discs is 0.1 mm or 0.2 mm. The smallest possible plate / disc thickness is 0.02 mm (20 μm). Larger thicknesses (eg 1 mm) can be obtained by folding several (eg 5) layers of a typical thickness (e.g., 0.2 mm).
