Abstract

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. © 2017 Elsevier B.V.
