Descripción

Descripción general

Calcium carbonate is a calcium salt commonly found in shells and skeleton of marine animals.[1] It is an inexpensive, non-toxic and easily available reagent with a wide range of applications such as uptake of CO₂ and extraction of heavy metals and arsenic from ground water.[2][3] Its crystals exist as 3 different polymorphs namely, calcite, aragonite, and vaterite.[3] The kinetics of pyrolysis of calcium carbonate under non-isothermal conditions have been investigated.[4]

Aplicación

Calcium carbonate may be used:

• As a pore generating agent to prepare porous ceramics.[5]
• As chelometric standard for the standardization of EDTA solution.[6]
• To extract aluminium by microwave induced thermal activation of coal fly ash (CFA).[7]
