An article about the chemical compound strontium oxide

Strontium oxide (SrO) is a chemical compound consisting of strontium and oxygen. It is a white to yellowish crystalline solid that is highly reactive with water, forming strontium hydroxide.

Properties[edit]

Strontium oxide is an alkaline earth metal oxide with a molecular weight of 103.62 g/mol. It has a melting point of 2,531 °C and a boiling point of 3,200 °C. The compound is ionic in nature and forms a cubic crystal structure.

Production[edit]

Strontium oxide is typically produced by the thermal decomposition of strontium carbonate (SrCO_) or strontium nitrate (Sr(NO_)_). The reaction involves heating the precursor compound to a high temperature, resulting in the release of carbon dioxide or nitrogen dioxide, respectively, and leaving behind strontium oxide.

Applications[edit]

Strontium oxide is used in various industrial applications. It is a key component in the production of strontium ferrite magnets, which are used in loudspeakers and other electronic devices. Additionally, SrO is used in the manufacture of glass, particularly cathode ray tube (CRT) glass, where it helps to block X-ray emissions.

Reactivity[edit]

Strontium oxide reacts vigorously with water to form strontium hydroxide (Sr(OH)_), releasing a significant amount of heat in the process. This reaction is typical of alkaline earth metal oxides.

Safety[edit]

Handling strontium oxide requires caution due to its reactivity with water and its ability to cause skin and eye irritation. Proper personal protective equipment (PPE) such as gloves and goggles should be worn when working with this compound.
