Diffusion and Redox Reactions of Sulfur in Silicate Melts Available to Purchase

Although large-scale transport in magmas is usually controlled by convection, diffusion of sulfur in silicate melts, nevertheless, plays a crucial role in the kinetics of various magmatic processes. The most important process is probably the degassing of magmas and melts initiated by an oversaturation of the melt with respect to dissolved volatiles. Such oversaturation can be caused in nature, i.e., by decompression when a magma ascends to the Earth surface. But the degassing of melts is also of major interest for technical applications, e.g., during fining of melts in industrial glass production. The kinetics of volcanic eruptions and the fining...
