Product Description

97%  industry grade  strontianite powder density 3.7g/cm3 is a mainlyused as ferrites for permanent magnets 






           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.








       It is used in the manufacturing of strontium ferrites for permanent magnets


which are used in Loudspeakers and door magnets.
