In the world of pyrotechnics, strontium chloride is a red coloring agent, and it imparts a more vibrant, striking red colour to a flame. It is also used as a precursor to other strontium compounds. For example, it is a source of strontium chromate, a chemical compound used in corrosion prevention of aluminum.
Among the ions found in water, strontium chloride has a high water solubility. This makes it a good choice for use in pyrotechnics and glass-making. The aqueous solution of strontium chloride is a neutral compound.
Another important advantage of strontium chloride is its low toxicity. It is less toxic than barium chloride. However, it is more toxic than calcium chloride. So, it is usually used in very small quantities.
As a general rule, strontium chloride has a very slow rate of reaction with water. If you want to make strontium chloride aqueous, you need to use a little bit of hydrochloric acid.
Strontium chloride can also be prepared by double displacement with sodium salts. Once the solution has a pH value of about 4-5, it is considered to be dehydrated. At that point, the remaining strontium is distributed in the skeleton of the bone.
Strontium chloride hexahydrate is slightly soluble in ethanol and acetone. The hexahydrate is used as a catalyst in the conversion of ketones to dihydroperoxides.
Strontium chloride is widely available in many different grades and volumes. American Elements manufactures a wide variety of standard grades, a custom grade and a chemical conversion tool.
