MICA powder is a high-grade reagent supplied by Research Lab Fine Chem Industries. The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage. It is available in the form of solid lustrous crystalline plates, which are insoluble in cold water. It is stable as long it is stored as per the recommended storage conditions. MICA is non-corrosive in presence of glass. The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. CAS No. 12001-26-2 Quantity provided: 500 gm/bottle Molecular formula: H4Al6K2O24Si6 Molecular weight: 797 g/mol The commercially important micas are muscovite and phlogopite, which are used in a variety of applications. The crystalline structure of mica forms layers that can be split or delaminated into thin sheets usually causing foliation in rocks. These sheets are chemically inert, dielectric, elastic, flexible, hydrophilic, insulating, lightweight, platy, reflective, refractive, resilient, and range in opacity from transparent to opaque. Mica is stable when exposed to electricity, light, moisture, and extreme temperatures. It has superior electrical properties as an insulator and as a dielectric, and can support an electrostatic field while dissipating minimal energy in the form of heat; it can be split very thin (0.025 to 0.125 millimeters or thinner) while maintaining its electrical properties, has a high dielectric breakdown, is thermally stable to 500 C (932 F), and is resistant to corona discharge. Muscovite, the principal mica used by the electrical industry, is used in capacitors that are ideal for high frequency and radio frequency. Phlogopite mica remains stable at higher temperatures and is used in applications in which a combination of high-heat stability and electrical properties is required.
