97% industry grade strontianite powder density 3.7g/cm3 is a mainlyused as ferrites for permanent magnets
►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
1. Strontium carbonate coarse powder is used in the production of glazes,
frits and for production of strontium pigments. Another application for strontium
carbonate coarse powder is the production of special glass.
2.Strontium carbonate fine powder is used in the production of ferrites for
permanent magnets, and in Zinc electrolysis for removal of lead. Strontium
carbonate fine powder is also used in the production of strontium chromate.
3. Strontium carbonate granular is used in the production of display glass
and other glass. Strontium carbonate granular is also used in the metallurgy.
4. Strontium carbonate standard powder is used in the production of ferrites
for permanent magnets. Strontium carbonate standard powder is also used for the
production of glazes and enamel frits.
►Application
It is used in the manufacturing of strontium ferrites for permanent magnets
which are used in Loudspeakers and door magnets.
