摘要：

The purpose of this paper is to report on the results obtained with different vitreous materials: a German borosilicate glass (VG98/12), its local counterpart (Simil VG), a natural aluminosilicate volcanic glass (VV), and two German aluminoborosilicate glasses (SG7 and SG8), with incorporated simulated high-level liquid wastes (HLLW), LWR and PHWR types. The optimal conditions for pressure and pressureless sintering are given, as well as the simulation, formulation and preparation of the simulated HLLW type PHWR, as well as the corrosion and thermal behavior of the waste forms obtained. Leaching rates of aluminosilicate (VV) and aluminoborosilicate (SG7) glasses were about 10(-2) g m(-2) d(-1), that is one order of magnitude lower than those for borosilicate glasses. The devitrification of aluminoborosilicate glass (SG7) increased leaching rate by a factor of 3 for Mo.
