Complete High purity Rare Earth (Lanthanides) - Set in Ampoules
*** All 16 fascinating elements in one set! ***
Thank you for watching our elements. Working with the "building blocks" of our universe is more than dusty science, it is in fact a deep and sometimes expensive passion.
My slogan is "The purer, the better.." - If you really want to know the physical and chemical properties of a material, then even the purest is just good enough. Here we sell incomparable quality at lowest prices.
If you are not satisfied, you get your money back!

16 Elements with up to 2g of 3N to 5N materials per ampoule (crystals or cast pieces, no powder or filings!) sealed under argon!
If you want your air sensitive Rare Earth Metals to shine forever, this is the right choice!
We replace and refill broken Ampoules from this set for free - even after years!
Each set is made by hand from professional technician with many years of experience !

When you look at the Periodic Table , there is a block of two rows of elements located below the main body of the chart. These elements, plus lanthanum (element 57) and actinium (element 89), are known collectively as the rare earth elements or rare earth metals. Actually, they aren't particularly rare, but prior to 1945, long and tedious processes were required to purify the metals from their oxides. Ion-exchange and solvent extraction processes are used today to quickly produce highly pure, low-cost rare earths, but the old name is still in use. The rare earth metals are found in group 3 of the periodic table, and the 6th (5 d electronic configuration ) and 7th (5 f electronic configuration) periods. There are some arguments for starting the 3rd and 4th transition series with lutetium and lawrencium rather than lanthanum and actinium.
There are two blocks of rare earths, the lanthanide series and the actinide series. Lanthanum and actinium are both located in group IIIB of the table. When you look at the periodic table, notice that the atomic numbers make a jump from lanthanum (57) to hafnium (72) and from actinium (89) to rutherfordium (104). If you skip down to the bottom of the table, you can follow the atomic numbers from lanthanum to cerium and from actinium to thorium, and then back up to the main body of the table. Some chemists exclude lanthanum and actinium from the rare earths, considering the lanthanides to start following lanthanum and the actinides to start following actinium. In a way, the rare earths are special transition metals , possessing many of the properties of these elements.
