The three corrosive earths are calcareous earth, strontian and baryta, or it may be said that the first would be salt, the second Inflammable, and the third, metal.
Now as the hardness and specific gravity of carbonate of strontianis greater than that of carbonate of lime, we can see a reason why arragonite should be heavier and harder than calcareous spar.

Lime is a compound of calcium and oxygen, magnesia of magnesium and oxygen, barytes of barium and oxygen, and strontian of strontium and oxygen.

This strontian was on the south side of Moss Island, in a horizontal vein of three feet in thickness, and from forty to fifty feet in length.
I find that strontian is much more extensively interspersed through the rock formations of this region than I had heretofore conceived.
Stars containing nitrate of strontian must be damped, either with lac solution, or wax solution; anything containing water destroys the colour.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "strontian" in a variety of sentences. We hope that you will now be able to make sentences using this word.
