Determination of the chemical composition of fiberglass silicate materials by the differential dissolution method

摘要

The standardless method of differential dissolution (DD) was used for determining the chemical composition of aluminosilicate and zirconium silicate glass-fiber clothes at different stages of their preparation and modification. Conditions for the detection, identification, and quantitative determination of various forms of heterogeneity in the elemental, phase, and surface compositions of these materials are considered. The distribution of the elements that constitute the glass-fiber clothes between various forms-surface ion-exchange (Na), hydrated (Al, Si), and framework (Al, Si) species-was quantitatively determined for the first time.
