Product Description

SrCO3 97% Strontium carbonate powder used as an colorant in fireworks Molecular weight 147.63



        Strontianite is a Colorless or white rhombic crystalline powder.Being a


carbonate, it is a weak base and therefore is reactive with acids. It is otherwise


stable and safe to work with. It is practically insoluble in water (1 part in


100,000). The solubility is increased significantly if the water is saturated with


carbon dioxide, to 1 part in 1,000. It is soluble in dilute acids.


Other than the natural occurrence as a mineral, strontium carbonate is


prepared synthetically in one of two manners. First of which is from naturally


occurring celestine also known as strontium sulfate (SrSO4) or by using soluble


strontium salts by the reaction in solution with a soluble carbonate salt (usually


sodium or ammonium carbonates).For example if sodium carbonate was used in


solution with strontium nitrate:Sr(NO3)2 + Na2CO3 → SrCO3 + 2 NaNO3

►Types of powder

     •Strontium carbonate coarse powder


      Strontium carbonate fine powder

      The most common use is as an inexpensive colorant in fireworks.


Strontium and its salts emit a brilliant red color in flame. Unlike other


strontium salts, the carbonate salt is generally preferred because of its cost


and the fact that it is not hygroscopic. Its ability to neutralize acid is also very


helpful in pyrotechnics. Another similar application is in road flares.
