Strontium Oxide is created when the following chemical reaction occurs: SrO + H2O -----> Sr(OH)2. There is not much information of spotlight on this compound. However, it is most commonly known to be a coating on ceramic creations. While this is the most commonly known use, SrO is also used for electronic mechanisms.



Strontium oxide is a basic substance that is usually in the form of a white thick powder. It has cubic shaped crystals. Completely insoluble, it has a high melting point of 2,531° C (4,588° F) and also a high boiling point 3200 °C (5792 °F). With only a few uses, strontium oxide is not that commonly known. It's properties display that it is non-flammable and not incredibly dangerous. As a compound containing Strontium, it reacts with water and is helpful in a short list of uses. [2]


Strontium Oxide can react with many things, and it is created when strontium reacts with oxygen. It does not conduct electricity. But can become somewhat electrically conductive when associated with fuel cells.


Strontium does not have many uses, but it does have a few. Its main use is to make a covering or better finish on clay poetry. This is one of the most simple uses of the compound, but there are other uses like electronic uses. As an oxide, Strontium Oxide is an aqueous solution, making it stable which is useful for clay pots and ceramic supplies.[3]


Strontium Oxide can be purchased. It is more reactive than carbonate and hydroxide products, therefore being more rare and harder to find for sale.[4]
