SrCO3 97% Strontium carbonate powder used as an colorant in fireworks Molecular weight 147.63
►Description
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
There have 4 types of powder for strontium carbonate .
•Strontium carbonate coarse powder
•Strontium carbonate fine powder
•Strontium carbonate granular
•Strontium carbonate standard powder
►Application
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.

►Notice
Eye Contact: Immediately flush eyes with running water for at least 15 minutes,
keeping eyelids open. Cold water may be used.
Skin Contact: After contact with skin, wash immediately with plenty of water.
Gently and thoroughly wash the contaminated skin with running water and non-
abrasive soap. Be particularly careful to clean folds, crevices, creases and groin.
Cover the irritated skin with an emollient. If irritation persists, seek medical
attention.
Serious Skin Contact: Not available.
Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate
medical attention.
Serious Inhalation: Not available. Ingestion: Do not induce vomiting. Loosen tight
clothing such as a collar, tie, belt or waistband. If the victim is not breathing,
perform mouth-to-mouth resuscitation. Seek immediate medical attention.
