The purpose of 97% white Strontium carbonate powder is making superconductors CAS NO 1633-05-2

►Description

Strontium carbonate (SrCO3) is a white,odorless, tasteless powder.It is the

carbonate salt of strontium that has the appearance of a white or grey powder. It

occurs in nature as the mineral strontianite.

Strontium carbonate is a white, odorless,tasteless 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.

►Preparation

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

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

Strontium carbonate is also used for making some superconductors such as

BSCCO and also for electroluminescent materials where it is first calcined into SrO

and then mixed with sulphur to make SrS:x where x is typically europium. This is

the famous "blue/green" phosphor which is sensitive to frequency and changes

from lime green to blue Other dopants can also be used such as gallium, or yttrium

to get a yellow/orange glow instead.
