He is credited for proposing that pegmatites form through the interaction of silicate melt and supercritical water.

The first technique depends on the phenomenon of "supercritical" water.

Oily substances, which do not mix with water at ordinary temperatures and pressures, are easily soluble in supercritical water.

And salts, which do dissolve in ordinary water, are separated out in supercritical water.

That would seem to leave that part of the market to supercritical water.

Use of supercritical water instead of acetic acid as a solvent diminishes environmental impact and offers a cost advantage.

While it may be possible to use supercritical water as a coolant in a fast reactor, this would require a very high pressure.

As the critical point is approached, solubility drops markedly to a few ppm, and salts are hardly soluble in supercritical water.

Superheated water, along with supercritical water, has been used to oxidise hazardous material in the wet oxidation process.

The supercritical water has now given up enough energy through expansion that it is in a vapor state.
