Calcite - an overview | ScienceDirect Topics

Using a microindenter to pressure dissolve calcite was done in a few studies (Croizé et al., 2010c; Zubtsov et al., 2005).The principle of the experiment is to leave a loaded rigid indenter over a single calcite crystal and let pressure solution dissolve the area under stress below the indenter (Figure 3.9).The depth of the hole is monitored as a function of time using either optical or high ...

The Acid-Effervescence of Calcite | Rock & Gem Magazine

That same reaction occurs when acid contacts calcite. Using hydrochloric acid (HCl) as an example, calcite effervesces vigorously when the acid's highly reactive chlorine ions (Cl 1-) break its weak ionic bonds and replace its carbonate radicals. This reaction is stated by the formula CaCO 3 + 2HCl = CaCl 2 (calcium chloride) + H 2 O (water ...

Application of microbially induced calcite precipitation to prevent ...

Purpose Soil loss by rainfall is a serious problem in civil and environmental engineering. In this study, microbially induced calcite precipitation (MICP) was applied to reduce rainfall-induced soil loss. Furthermore, the effects of particle size and organic matter content were investigated. Materials and methods A mixture of Sporosarcina pasteurii, 450 mM urea, and 450 mM calcium ions was ...
