Implication

Experimental study demonstrates that hydration route and agents govern the crystal size and porosity of eggshell-derived calcium hydroxide, suggesting tunable synthesis for specific applications.

Key Points

To examine how synthesis routes, hydration agents, temperatures, and liquid-to-solid ratios influence the physicochemical characteristics of calcium hydroxide produced from eggshell waste.
Converted eggshell-derived calcium oxide into calcium hydroxide using hydrothermal and bubble techniques across temperatures between 150 °C and 230 °C.
Varied the hydration agents (pure water vs. ethanol-water mixture) and solid-to-liquid ratios.
Evaluated structural, morphological, and surface properties using characterization methods including X-ray diffraction.
The bubble technique produced smaller crystallites, whereas hydrothermal processing at sample 230H04 (10 mL) yielded the largest crystallite size at 59.50 nm.
Sample 230B31 achieved the highest surface area (31.14 m²/g), while sample 150H31 reached the maximum pore volume (0.19 cm³/g).
Lower hydrothermal operating temperatures favored greater porosity and higher surface area.
