Effect of annealing conditions on the structure, phase and granulometry composition, and reflectance spectra and their changes on irradiation for calcium silicate powders
High-temperature annealing of hydrated forms of calcium silicate produced in the multicomponent system CaCl2-Na2SiO3-H2O yields the formation of a heterophase structure containing high temperature phases of pseudo-wollastonite and silica. Under these conditions, it is observed that there is an increase in the calcium silicate crystal lattice energy, particle size, reflection coefficient in the visible and near-IR spectral ranges, and radiation stability of the synthesized powders. The improved characters make the work useful, interesting and important. (C) 2017 Elsevier B.V. All rights reserved.
