abstract = "High resolution electron microscopy, analytical electron microscopy and selected area electron diffraction are used to establish the crystallo-chemical mechanisms by which simulated high level waste enters Synroc. It is shown that waste species are incorporated largely as a non-continuous solid solution. In other words, simple isomorphic substitution of waste elements in place of matrix cations, i. e. the classical continuous solid solution, does not operate (or is only significant at very low waste levels of radwaste). It is believed that the mechanism of structural modification will endow Synroc with considerable flexibility to respond to chemical changes in the wastestream. Other ceramic materials currently being evaluated as possible wasteforms (viz. sphene glass-ceramics and APO//4 phosphates) are also likely to possess this capacity.",
