1pc 10g Weight High Purity Osmium Metal Bead, 99.95% Pure Melted Os Irregular Ball for Lab Experiments and Periodic Table Densest Element Specimen Collection Scientific Research

Osmium is a heavy platinum group precious metal and a stable element with extremely low content in the earth's crust. Its annual production is less than one ton, which is very rare in the world. Osmium is a highly dense element in nature, with a density of up to 22.59 g/cm3 and a melting point of 3045 ℃. Due to the extremely high melting point of osmium and the possibility of producing osmium tetraoxides if not controlled properly during the melting process, osmium melting is relatively difficult.Moreover,osmium raw materials are already very rare and difficult to obtain, so dense osmium beads or ingots obtained through smelting are extremely rare.

• Osmium, as the metal with the highest density in the periodic table (22.59g/cm ³), can intuitively demonstrate the physical properties of the "densest element" with its small volume
• 1pc of 10g molten osmium metal beads with a purity of 99.95%.
• Osmium is very suitable as the best gift for collectors of periodic table samples.
• Osmium, as an elemental specimen, exhibits the density and periodicity of metals, making it suitable for research institutions, school teaching, or enthusiasts of element collection.
• High temperature melting technology is used to produce irregular spheres with a dense and glossy surface, avoiding interference from oxide layers on experimental data.
