Strontium oxide (SrO)(CAS: 1314-11-0)

Strontium oxide (SrO) is a white or pale yellow crystalline solid. It has a high melting point and is slightly soluble in water, forming strontium hydroxide. Chemically, SrO is a basic oxide that readily absorbs carbon dioxide from the air, forming strontium carbonate. Its molecular weight is approximately 69.62 g/mol and it is reactive with acids.

Strontium oxide can be synthesized by heating strontium carbonate or strontium hydroxide. The typical reaction involves the calcination of strontium carbonate (SrCO3) at high temperatures (about 600°C), which results in the formation of SrO. This process is highly exothermic and requires careful temperature control.

Strontium oxide finds applications in various industries. It is used in the production of glass and ceramics due to its ability to enhance durability and improve optical properties. In the pharmaceutical industry, it acts as a component in certain formulations. Additionally, it is used in the manufacturing of sensors and semiconductors, where its stability and reactivity make it suitable for these applications.

When handling strontium oxide, it is essential to take safety precautions. Wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. Work in a well-ventilated area or a fume hood. Avoid contact with skin and eyes. In case of a spill, use appropriate absorbent materials and dispose of them according to regulatory guidelines. Always refer to the Safety Data Sheet (SDS) for detailed handling instructions.
