title: Analytical study of raw Swarna Makshika (Chalcopyrite) and its Bhasma through TEM and EDAX.
abstract: Ayurveda, the Indian System of Medicine deals with a number of metals and minerals. Swarna Makshika (SM), a chalcopyrite one such minerals has iron (Fe), copper (Cu), and sulphur (S) as major ingredients along with other trace elements of therapeutic importance. Studies related with characterization of SM are very few. In the current study SM and SM Bhasma were analysed through Transmission Electron Microscope (TEM) and Energy Dispersive X-Ray Analysis (EDAX). Analysis reveals the presence of iron, copper, and sulphur in SM. In addition to these elements, SM Bhasma found to contain Potassium, Magnesium, Aluminum, and Silicon in trace amount. TEM study reveals that, grain size of the SM (5-10 microns) is significantly reduced in SM Bhasma to 50-200 nm.
