Mica refers to naturally occurring layered silicate minerals characterized by their distinctive platelet-like structure and available in various mica types. Industrial applications primarily focus on light-colored muscovite and dark-colored phlogopite mica. Both mica types are carefully processed and refined by HPF The Mineral Engineers.
The products of the Quarzwerke division HPF are sold under the brand names TREMICA® (surface-treated muscovite mica) and TREFIL® 1232 (untreated and surface-treated phlogopite mica).
Technical properties:
- density: 2.85 g/cm³
- hardness: 2.5 (Mohs)
- high resistance to high temperatures
- low oil absorption
- high aspect ratio (1:30)
- lamellar-shaped particles
- pH value: 9.5
- thermal expansion coefficient of muscovite: 7*10-6/K
- thermal expansion coefficient of phlogopite: 27*10-6/K
We would be pleased to advise you on potential applications for TREMICA® and TREFIL®. Please do not hesitate to contact us for further information!
