Petrographical characteristics of calcium based absorbent

Lead calcium titanate nanoparticles (PCT-NPs) were synthesized by the modified sol-gel method. The mixed metal alkoxide precursor was prepared by moderate refluxing using lead acetate, calcium acetate, titanium iso-propoxide and 2-methoxyethanol. The properties of PCT-NPs were studied as a function of calcination temperatures.

Herein, we demonstrate a novel aqueous-phase calcination-free process to precipitate Ca(OH) 2 from saturated solutions at sub-boiling temperatures in three steps. First, calcium was extracted from an archetypal alkaline industrial waste, a steel slag, to produce an alkaline leachate.
