Glass-Ceramics Obtained by the Crystallization of Basalt
Apstrakt
The possibility to obtain glass-ceramics from basalt from the locality on Vrelo (Kopaonik mt.) is shown in this paper. The parent rock was ground to fraction -0.4 +0.1 mm, and then melted at 1250 - 1300 degrees C. The crystallization melted bazaltic glass at 950 degrees C during the time interval of 3 hours caused synthesis of a glass-ceramic material with a microstructure that has excellent mechanical properties according to the determined dynamic modulus of elasticity and uniaxial compresive strength. The phase composition of. the obtained glass ceramic material was determined by XRPD using Rietveld refinement and SEM. Two phases were found: pyroxene which corresponds to omphacite of the composition (Na(0.199) K(0.180) Ca(0.471) Mg(0.249))(1.1)(Mg(0.271)Fe(0.299)Al(0.430))(1.0)(Si(1.704)Ti(0.046)Al(0.250))(2.0)O(6) and glass with on approximate relationship 69:31.
