Mineraloško-kristalografske karakteristike distensko-korundske sirovine iz ležišta Bobološ na različitim temperaturama
Mineralogicaly-crystallographical characteristics of the kyanite-corundum mineral raw material from the ore deposit Bobološ at different temperatures
Апстракт
Powder diffraction patterns were indiced and there were determined qualitative, semiquantitative compositions of the mineral raw material, “baked” mineral raw material and brick. There were established changes of the mineral compositions, mineral transformations and precrystallizations at different temperatures. There were calculated and compared unit cell dimensions of the kyanite, corundum, rutile, andalusite, sillimanite and mullite. At corundum and rutile they are mostly unchangeable and in the range of the standard error. Sillimanite and mullite have in the brick samples ao-axis bigger and bo-axis smaller than in the “baked” mineral raw material samples, while co-axis and volume-Vo remained almost constant. That indicate to the partially thermal expansion in the ao-axis direction against bo-axis and to the increase of the Al2O3 content in the mullite's structure from the brick at respect to the mullite from the “baked” mineral raw material.
Regard to the literature datas, smalle...r unit cell dimensions has kyanite, corundum and mullite, bigger andalusite and sillimanite, while rutile has approximatively equal. The most quantity mineral in the samples of the “baked” mineral raw material and brick is mullite, which indicate to their excellent characteristics and usage. At basis of the mineral composition in the “baked” mineral raw material and brick samples it was estimated Al2O3 content of about 60%.
