- 論文の詳細を見る
The sol-gel-derived diopside gels of the composition 25mol%CaO-25mol%MgO-50mol%SiO<SUB>2</SUB> are prepared adding hydrochloric acid of 1 to 4 mol/dm<SUP>3</SUP> concentration in the basic step, and the crystallization behavior of the gels during heating is investigated using thermal differential analysis (DTA-TG), X-ray diffraction and Fourier transform infrared spectroscopy. The results show, that the addition of hydrochloric acid leads to lower temperatures of glass formation and crystallization, due to the ristriction of calcium carbonate formation, and that the suitable concentration for the single phase crystallization is 3 mol/dm<SUP>3</SUP>.
