内容記述 |
In this study, we attempted to synthesize Ca10Si6O21Cl2 in a reducing atmosphere using CaCO3, SiO2, and CaCl2‧2H2O as starting materials and by firing in a 5% H2 stream or with activated carbon. In order to confirm that the reducing atmosphere was realized, CaSO4‧2H2O or Eu2O3 was added as a starting material, and the introduction of sulfur or europium into the sample and their states in the sample were examined. Ca10Si6O21Cl2 phase was produced by both firing methods, but there were many impurities when firing in a 5% H2 stream, while there were few impurities when firing with activated carbon. Sulfur was detected by energy dispersive spectroscopy in the sample obtained by adding CaSO4‧2H2O as a starting material and firing with activated carbon, but SO42- could not be confirmed by Raman scattering spectroscopy. The sample obtained by adding Eu2O3 as a starting material and firing with activated carbon showed green fluorescence originated from Eu2+ by ultraviolet irradiation. When activated carbon is used, the Ca10Si6O21Cl2 phase can be successfully synthesized in a reducing atmosphere. |
