Strontium is a chemical element with the symbol Sr and atomic number 38. It is a soft, silvery-white metal that is highly reactive, and as such, it is not found in its elemental form in nature. Despite this, strontium is an important element that has a number of applications, particularly in the field of pyrotechnics.
The melting point of strontium is 777°C (1,431°F). This relatively high melting point means that strontium can be used in a variety of high-temperature applications, such as in the production of pyrotechnic flares.
In these flares, strontium is combined with other chemicals to produce a bright red flame that is highly visible, even in daylight. The high melting point of strontium makes it a popular choice for use in flares because it allows the material to burn at a high temperature for an extended period.
Strontium is also used in the production of strontium salts, which have a number of applications in medicine and industry. For example, strontium-90 is a radioactive isotope that is used in the treatment of certain types of cancer. Strontium salts are also used in the production of ferrite magnets, which are used in a variety of electronic applications.
