Chain–ring interconversion in metasilicates
Abstract
Theoretical studies indicate that lattices of the chain and ring varieties of CaSiO3 fit together with only slight mis-match; high resolution electron microscopic studies of a sample undergoing conversion from chain- to ring-structure, however, indicate that intergrowths do not occur and, instead, the chain structure recrystallises via a glassy phase into ring silicate to the same composition.
