Nepheline As a Source of Amorphous Phases in Supergene Processes

摘要

In order to specify the effect of technogenic factors on the composition of natural waters, the behavior of nepheline particles < 0.002 mm in size at a temperature of 18-20℃ and pH 7.4-8.6 has been studied. The results obtained show that finely ground nepheline passes into an amorphous phase over a few days or months. The study is based on the data on natural and technogenic water in the area of the Khibiny alkaline pluton.
