说明

碳酸钙是一种钙盐，常见于海洋动物的外壳和骨骼中。它是一种廉价、无毒且容易获得的试剂，具有广泛的应用，如吸收CO2和从地下水中提取重金属和砷。其晶体以3种不同的多晶型存在，即方解石、文石和球霰石。研究了碳酸钙在非等温条件下的热解动力学。

一般描述

Calcium carbonate is a calcium salt commonly found in shells and skeleton of marine animals. 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. Its crystals exist as 3 different polymorphs namely, calcite, aragonite, and vaterite. The kinetics of pyrolysis of calcium carbonate under non-isothermal conditions have been investigated.
 

应用

Calcium carbonate may be used:
  • As a pore generating agent to prepare porous ceramics.
  • As chelometric standard for the standardization of EDTA solution.
  • To extract aluminium by microwave induced thermal activation of coal fly ash (CFA).
