Vasili Samarsky-Bykhovets
Of Russian mining fame
Named the mineral samarskite
For which I have been named

Samarium's the first element
Named for a living person
0.274 in alpha form
On the ratio of Poisson

Discovered spectroscopically in 1853
By a chemist who was Swiss Later isolated in Paris
There was no commercial use for me before 1950's
With the advent of ion exchange separation technologies

My symbol's S & M
But I'm not really that kinky
My vicker's hardness registers
412 MegaPascals meekly

Samarium in Lindsay Mix
Was recently replaced
By Samarium-Europium-Gadolinium
Or SEG Concentrate
