Chemical and Mineralogical Studies of Magmatic Rocks of Uzbekistan for Obtaining Heat-Insulating Materials

Justification of the opportunities of obtaining silicate materials based on clay waste adsorbents

“…There are particular requirements for the initial raw materials for obtaining heatinsulating materials [13][14][15][16][17], which are listed in Table 2 below. 1) showed that sample 1.2 has a low content of silica and alumina, iron, calcium, alkali metals and carbonates according to Table 2, while sample 3.4 has a high content of chemical composition shows that it can be.…”

Investigation of thermal properties and composition on basalts of the Aydarkul deposit by methods DTA/DTG and X-ray diffraction

“…2., Table .1.) [12,[23][24][25]28]. The study of the process of thermal action on basalts, where the transformation of basalt rock occurs, is expressed through derivatograms.…”

“…At the same time, as a result of the destruction of the crystal structure of natural basalt, due to the heat treatment process, a second exothermic effect is manifested in the temperature range of 820-840 ° C. This phenomenon can be explained by the detection of three endothermic effects appearing in raw materials (at temperatures of 120-160 O C, 335-375 o C, 580-590 o C, respectively) and two exothermic effects (at temperatures of 300-450 o C and 700-720 O C). It is established that the shape of thermal curves is associated with the thermal insulation of raw materials and with the characteristics of the basalts of the Aydarkul deposits [25][26][27].…”

Physico-chemical studies of Arvaten basalt for the production of mineral fiber

“…The results of X-ray phase analysis [20,21] of experimental samples from the basalt of the Arvaten deposit showed that the main rock-forming mineral is albite (Fig. 1).…”
