Essentially,
Abhrak(Black Mica) is comprise of a number of other minerals, nutrients and
elements. These include magnesium, aluminum, silicon, oxygen and hydrogen.
Abhrak( Black Mica) is a mineral that appears black and shiny in appearance. It
is found mainly in granite and other metamorphic rocks.
The Abrak group represents 37 phyllosilicate
minerals that have a layer or platy texture. The commercially important Abrak
are muscovite and phlogopite, which are used in a variety of applications. Mica
Herbs value is base on several of its unique physical properties. The
crystalline structure of Abrak forms layers that can be split or delaminate
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. Abrak 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 Abhrak used
by the electrical industry, is used in capacitors that are ideal for high
frequency and radio frequency. Phlogopite Abrak remains stable at higher
temperatures (to 900 °C (1,650 °F) and is used in applications in which a
combination of high-heat stability and electrical properties is required.
Muscovite and phlogopite are used in sheet and ground forms.
Abhrak Benefits
Abhrak use in Ayurveda for respiratory, liver
and abdominal diseases, mental and psychomotor disorders. It has ability to
pacifying the all three doshas in body. Mica Herbs provides adequate energy to
the body and also has a calming effect on the body. This is prepared through
calcinations process.
It contains different chemical constituents
like Magnesium, Iron, Potassium, Calcium and Aluminum.
Ayurveda, the Hindu system of ancient medicine
prevalent in India, includes the purification and processing of mica in
preparing Abhrak, which is employ in treating diseases of the respiratory and
digestive tracts.
