Abstract

The traditional methods, we experimented, have unique advantages keeping ScCO2 in the primary material by simple, cost ineffective and high productive way, avoiding necessity of grinding a material to a smaller particles, using chemical salts. It is green, ecologically pure and ready to use for industrial production. In the world practice, in order to derive medical nanopowder ScCO2 is usually added to the target material either in gas or liquid form. In contrast to this, in the Mongolian traditional technology the thermal processing of medical material does not loose CO2 and keeps it in the target material. By this work, we aimed to prove that our experiment made on the basis of the traditional technology is performed at the current nanotechnological level and to explain it’s scientific substantiation by modern scientific expressions. Nano-sized medical raw materials has been derived from the medical quality natural spar (CaCO3) without the use of chemical salt. The theoretical base of the method consists in the transferring and keeping CO2 to a supercritical state during thermo-chemical processing of the spar at 900- 9500C. The ScCO2 has a form of solid solution that holds the properties of both gas and solid. Afterwards, with dissolving it in the cow milk, the solution is equalized by the solvents expansion with the decrease of temperature and creates amorphous crystal nanopowder. The size of the resultant product C3H3CaLuO6 was determined both by XRD and TEM analysis as to be 13.51 nm(Lu>13.09 nm).
