Various salts can be decomposed by heat or can react chemically with the surrounding atmosphere to form a metal or an oxide. An example of an oxide-forming salt is a hydrate of iron nitrate which is molten at about 50 degrees C and decomposes at about 200 degrees C. Decomposition in an oxygen atmosphere should ensure the formation of the higher oxide.
