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

►Specification

►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.
