Abstract[edit]
all for the identification and characterization of a salt necessary data, graphics and images are collected. primarily the properties of the individual salts under each salt are presented.
The structure of the salt systems is subject to the major anions.
The Salts[edit]
Here you will find a general overview of the salts. If you need detail information, please go to the pages of the salts. Recent reviews on salt and salt damage can be found at [Leitner.etal:2003]Title: Mauersalze und Architekturoberflächen

Carbonates[edit]
The carbonates are salts of the "carbonic acid"(H 2 CO 3 ). The main structural element is the planar complex anion [CO 3 ] 2 - . The carbonates have a number of characteristics that distinguish them well from other minerals / salts. The most important characteristic is that they all when treated with acids, decpmpose more or less easily under CO 2 . The alkali and alkali earth are colorless. Most of the other carbonates are usually colored pale, only the Schwermetallcarbonate can show strong colors (such as azurite). Noteworthy is the extremely high birefringence of the carbonates, which leads to higher order interference colors. Under thermal treatment, the carbonates dissociate mostly at temperatures between 500-900 °C. The solubility in water is relatively good, especially in carbonated water.
