Highest Quality V1 Muscovite Mica Disk 20mm Diameter 10pack AFM SPM Calibration

Highest Quality V1 Muscovite Mica Disk 20mm Diameter 10pack AFM SPM Calibration Electron Microscopy Sciences 71856-04.

This is a 10-pack of 20mm Diameter, 0.15-0.21mm thick muscovite Mica. New in OEM packaging.

Mica Sheets offer a clean surface for EM applications, carbon filming and particle spraying, as well as for AFM applications. There are two types of mica: muscovite and phlogopite. Generally, one differs from the other by color (Muscovite is Ruby, Green or White; Phlogopite is Amber, Yellow, or Silver). The maximum operating temperature for Muscovite is about 500-600°C and for Phlogopite is about 800-900°C. Our line consists of High Quality Muscovite Mica. This mica peels off very thin up to 0.0001" uniform layers, exposing "virgin" mica upon splitting.

Characteristics:

Muscovite, potash type mica, sometimes known as granitic mica, is the best of all micas in dielectric strength, perfection of cleavage, and transparency.

It has the following chemical formula: H2KAI3(Si04)3.

Quality Determination:

V-1: Clear - Hard, of uniform color, nearly flat, free of all stains, foreign inclusion, cracks, and other similar defects.

Applications:

In general, for those whom are using mica for the making of carbon support films, thin films coatings research, and some AFM studies where HOPG are used to taking place, the mica V-4 or V-5 is recommended. (Mica must always use freshly cleaved surfaces).

For AFM and SPM calibration, V-1 or V-2 is recommended. However, we believe that it is important that you know what kind of mica is being used in your lab. The information on the mica as given above should be used to make your choice.
