Abstract
Solid-state reaction between carbonate and/or oxide precursors is a simple method to prepare ceramic powders. However, a high calcination temperature is required for this method because of limited diffusion during calcination. In this paper, we describe that the formation of β-CaSiO3 by solid-state reaction is accelerated by water vapor. β-CaSiO3 powders have been prepared by solid-state reaction between CaCO3 and amorphous SiO2 as a raw material. Single-phase β-CaSiO3 was successfully prepared by one-step calcination at 800°C for 2 h in water vapor, while it seemed to be difficult to prepare the single-phase β-CaSiO3 by calcination in air. Water vapor-assisted solid-state reaction is likely to be applicable to prepare other functional ceramic powders at low temperatures.
