Mineral Trioxide Aggregate (MTA)

Strontium carbonate is a fine, white powder and its chemical formula is SrCO₃. Its properties similar to those of calcium carbonate (lime). SrCO₃ is very minute soluble in water. It mainly dissolves in acids, for example in hydrochloric acid and also develops carbon dioxide. Strontium is in the group of the alkaline earth metals. It is non-toxic  similar to calcium, which is in the same group.

Pyrotechnic devices are utilised in military and nonmilitary applications. Military pyrotechnic applications that contained strontium included tracer ammunition, military flares, and marine distress signals.

During the electrolytic production of zinc, strontium is used to abolish lead impurities. The addition of strontium carbonate in sulfuric acid to the electrolyte reduces the lead content of the electrolyte and of the zinc that is deposited on the cathode.

Strontium carbonate is extensively utilized for electronic applications. It is particularly used as addition in the production of glass cathode-ray tubes for TV and computer monitors (more than 65% of total production).

It is also combining with iron to make magnets. Strontium ferrite magnets have high coercive force, high thermal and electrical resistivity, and are chemically inert. They retain their magnetism well, are not adversely affected by electrical currents or high temperatures, do not react with most chemical solvents, resist demagnetization and are low density.
