PROCESSES OF HETEROPHASE CHEMICAL CONVERSION OF NATURAL QUARTZITES OF ARMENIA BY THE CHAIN REACTION EFFECT METHOD TO OBTAIN PROMISING MATERIALS

Abstract

It has been shown that natural quartzites of Armenia undergo effective heterophase chemical conversion under the effect of gas-phase chain reactions (CRE-method) to obtain high-silica raw materials with new properties and characteristics. Numerous experimental data indicate that the original quartzites are selectively and intensively processed and modified by the CRE-method. They are activated and enriched with deep and sufficient extraction of unnecessary impurities, a significant change in the crystal structure and surface of microparticles, as well as an improvement in a number of other important physical and chemical indicators.
