A defining characteristic of silicate melts is the degree of polymerization (tetrahedral connectivity), which dictates viscosity and affects compressibility. While viscosity of depolymerized ...

Basic silica glass has a tetrahedral structure with silicon in the center and four oxygen atoms at the corners. A tetrahedron is a triangular pyramid.
