Huge 50mm Terbium metal cube with over 1kg – 99.95% purity
We are leading manufacturer of metal density cubes of highest quality. Our cubes are famous for having perfect surface finish, sharp edges and exact size. Everything is made by master’s hand with love for details on our own workshop in Austria. We are often asked why our cubes cost about 3 – 5 times more than those from other sellers. Well…. you can buy a cheap car just for moving from one point to another – Or you fulfill your lifelong dream and buy the sports car you always wanted to have…
Using selected and high pure materials only, each density cube was lapped to 10x10x10mm to reach 1cm3 and 21.5×21.5×21.5mm (big 10cm3 cubes) in our lab with an accuracy of 0.01 millimeter. Each one separately ground and polished in a several hours lasting process. The cubes represent the theoretical density of the respective element by its weight.
Terbium, among the exclusive cohort of “rare earth” metals, holds a special place as one of the more elusive members. Often overshadowed by its more celebrated counterparts, it quietly resides as a minor constituent within the coveted ores of monazite and euxenite, both actively sought after, particularly in the mineral-rich landscapes of China, in pursuit of these exotic elements.
The image shows a 21mm cube but you can be sure that you get the big one.
