Separation of medical nanopowder from the natural minerals by ScCO
2
T
he traditional methods, we experimented, have unique advantages keeping ScCO
2
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 ScCO
2
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 CO
2
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 (CaCO
3
) without the use of chemical salt. The theoretical base of the method consists
in the transferring and keeping CO
2
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 C

was determined both by
XRD and TEM analysis as to be 13.51 nm(Lu>13.09 nm).
