The Possibilities Of Using Loess Clay Of Kattabog Deposit In The Production Of Ceramic Products, Ruzibaev Bahrom, Saloxidinova Salima

CHEMISTRY AND CHEMICAL ENGINEERING

The aim of the research was to determine the properties of loess clay in Kattabog deposit (Uzbekistan) to identify possible areas of use. Modern methods of physicochemical analysis are used: spectroscopic, x-ray phase, electron microscopic methods of analysis. The research results showed that the main phases of clay are hydromica, quartz, kaolinite, calcite and orthoclase. Based on the research, it can be stated that the clay of Kattabog deposit has good physical and technical properties and mineralogical composition, which is a valuable raw material for the production of various ceramics, bricks, tiles, majolica and other products.

CHEMISTRY AND CHEMICAL ENGINEERING

The aim of the relearn was to study the phase changes during crystallization of some compositions of biocompatible glasses obtained in the RO-CaF2-P2O5-Al2O3-SiO2 (R=Zn, Mg) system. For this purpose, crystallization of glasses in the range of 700-1000 °C was carried out and X-ray analysis was carried out. A change in the phase composition of crystallized glass with a change in crystallization temperature and composition has been established. During crystallization, the phases of whitlockite, zinc-substituted fluorapatite, fluorapatite, anorthite, and gahnite were identified.
