Nano-Tec Muscovit Mica Scheiben und Blätter sind gedacht für den Einsatz mit Scanning Probe Mikroskopen, in Elektronenmikroskopen und für Dünnfilmanwendungen. Das Nano-Tec Mica ist ein Muscovit der höchsten Güteklasse V-1. Das Muscovit wurde wegen seiner Spaltbarkeit und wegen dem Fehlen von Einschlüssen und Blasen gewählt. Es ist transparent oder transluzent mit einer rötlich bis pinken Farbe. Mica ist ein natürliches Mineral. Die Dichte beträgt 2,7 – 3 g/cm³. Es hat die chemische Formel Kal3Si3O10(OH)2. Das Nano-Tec Mica wird in einem der qualitativ hochwertigsten Vorkommen in Indien gewonnen.
Um Mica nutzen zu können, muss es direkt nach dem Abbau gespalten werden, um ein sauberes Substrat zu erhalten. Die frisch gewonnenen Substrate sind sauber und haben eine ebene und atomar flache Oberfläche, die ideal für die Herstellung von Kohlefilmen, AFM Substraten und für Dünnschichtanwendungen ist.
Die Standarddicke der Nano-Tec Muscovit Mica Scheiben und Blätter variiert zwischen 0,15 und 0,21 mm und ergibt mehrere dünne Schichten (0,02 mm) an frisch gespaltenem Mica. Mica spaltet sich auf der <001> Ebene. Methoden können sein:
Mica ist ein nichtleitendes Material, stabil in Wasser, inert gegenüber den meisten Säuren, Basen, Lösungsmitteln und ölen. Es kann bis zu Temperaturen um die 500-600°C eingesetzt werden.

Visual grading classification system description for sheet mica
The quality of muscovite mica is determined by visual inspection according to ASTM D351-571 from the highest quality V1 to the V12 (V-10A)
1. V-1: Clear - Hard, of uniform colour, nearly flat, free of all stains, foreign inclusion, cracks, and other similar defects.
2. V-2: Clear and Slightly Stained - Hard, of uniform color, nearly flat and may contain slight crystallographic discoloration, and very slight air inclusions in not more than one fourth of the usable area.
3. V-3: Fair Stained - Hard, of uniform color, may contain slight waves, slight crystallographic discoloration, and sligh air inclusions in not more than one-half of the usable area.
4. V-4: Good Stained - Hard, of uniform color, may contain medium waves slight crystallographic discoloration, and medium air inclusion in not more than two-third of the usable area.
5. V-5: Stained A Quality - Hard, may contain medium air inclusions, uniformly distributed in the usable area; slight green vegetable stains, medium waviness, and heavy waves if specified.
6. V-6: Stained B Quality - Hard, may contain heavy air inclusions and heavy waves, medium green vegetable stains, slight black and red dots (mineral) and clay stains.
