Physicochemical Studies of Raw Materials from the Far East Russia for Synthesizing Foam Glass and Protective Enamel Coatings

Аннотация

The physicochemical properties of silicon containing raw materials from Far East Russia which are suitable as a base for synthesizing foam glass and protective enamel coatings for oil and gas pipelines were investigated. The investigations of the chemical and phase compositions as well as the macro- and microstructure of diatomite from the Chernoyarskoe deposit, opoka from the Botchinskoe deposit and quartz sand from the Chalganskoe deposit established that the most suitable raw material for the synthesis of high-quality glass materials by means of energy and resource conserving technologies is Chernoyarskoe diatomite, which contains amorphous silica, quartzite, clay impurities, opal, and very small quantities of calcite, mica, and zeolite.
