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.

Calcination Wikipedia

The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.
