Abstract
Ge-S-I glasses have been prepared. As I is increased, so the glass tra nsformation temperature and onset temperature of mass loss decrease. M elt viscosities, in the range 10(7)-10(10.7) Pa s, have been determine d via penetration viscometry, and isoviscous points are at a lower tem perature as I increases. The viscosity results are discussed in relati on to melt fragility and structure.
