Nitrate salts[edit]
Author: Hans-Jürgen Schwarz
back to SaltWiki:Portal
The nitrate salts most frequently found in buildings and monuments are listed. The various salt phases are discussed in detail on separate pages, their occurrence and their deterioration potential is discussed and the weathering patterns are illustrated on separate pages.
