The effect of pressure on melt viscosity was investigated in the system NaAlSi3O8-CaMgSi2O6 (Ab-Di) at pressures from 0.1 to 400 MPa using a parallel plate viscometer. The new measurements in the high viscosity range of 108.5 -1011 Pa·s are consistent with previous data obtained at high...

29Si MAS-NMR spectra are presented for a series of glasses on the join CaMgSi 2O 6 NaAlSi 3O 8. The spectra are broad, unresolved and symmetrical. The chemical shifts, Δ 29Si, depart significantly from a simple linear mixing model near X NaAlSi 3O 8 = 0.8 and several possible ...
