1978 Nature 3 Aug. 413/1 Whereas glassified waste may devitrify when exposed to ground water at high temperature and pressure, thus exposing a large surface area for the dissolution of the radionuclides in the glass, the new mineral—‘synroc’—should be as stable as a natural rock.

1980 New Scientist 3 July 9/2 In the Synroc process the radioactive wastes are trapped in the crystal lattices of the minerals of the synthetic rocks and so are completely immobilised.
