摘要
The results of investigations of the behavior of analcime-containing rocks of Timan (Komi Republic) at high temperatures (1200 - 1280 degrees C) are brought forward. The mineral composition and physical characteristics of the resulting ceramics were determined: apparent density, water absorption, open porosity, and thermal conductivity. The influence of the mineral composition of the initial analcime-containing rocks on the foaming capacity and physical characteristics of fired ceramics is demonstrated. Porous materials with low apparent density (0.37 - 0.39 kg/m3), water absorption (up to 4.3%), and thermal conductivity (0.09 - 0.10W/(m center dot K)) have been obtained. The results show the prospects of using analcime-containing rocks of a certain mineral composition for the production of heat-insulating foam materials.
