Calcium carbonate is an inorganic salt used as an antacid. It is a basic compound that acts by neutralizing hydrochloric acid in gastric secretions. Subsequent increases in pH may inhibit the action of pepsin. An increase in bicarbonate ions and prostaglandins may also confer cytoprotective effects.

A low molecular weight organic molecule, 1,3-diamino-2-hydroxypropane-N,N,N′,N′-tetraacetic acid, has been found that it could stabilize amorphous calcium carbonate (ACC) for at least three...
Abstract—We compare mid- and far-infrared attenuated total reflectance spectra for calcite and aragonite, which are two polymorphs of calcium carbonate, CaCO3, in order to demonstrate which spectral feature changes can be attributed to phase (crystal structure) differences.

2017年1月1日 · ATR-FTIR (attenuated total reflectance Fourier transform infrared) spectroscopy can be used as a rapid and economical tool for qualitative identification of carbonates, calcium sulphates, oxides and silicates, as well as quantitatively estimating the concentration of minerals.
Water, sulfur dioxide and nitric acid adsorption on calcium carbonate ...
Calcium carbonate (CaCO 3) is a reactive component of mineral dust aerosol as well as buildings, statues and monuments. In this study, attenuated total reflection (ATR) and transmission Fourier transform infrared spectroscopy (FTIR) have been used to study the uptake of water, sulfur dioxide and nitric acid on CaCO 3 particles at 296 K.
The non-crystalline forms of calcium carbonate, which are better known by the name amorphous calcium carbonates (ACCs), are isotropic in polarized light and do not diffract X- rays.
