## Description

Moderock Osmium Metal Elements Periodic Table, Mirror Finished Density Cubes Collection, Purity 99.95%, Weight 21.5g/0.76Oz (Os Cubic 10mm/0.39")

## Features

- osmium metal, precious metal periodic table cubic, osmium cubic, high purity osmium target, 10mm, Os ≥ 99.95%, made a slight chamfer treatment
- the actual density of 20.5 ~ 21.7 or so (powder sintering process reasons, so difficult to process the metal can not reach the theoretical density, only as close as possible. At the same time, due to each batch of production process parameters will be a little different, so the density will also be some differences), at the same time, due to the size of the existence of positive and negative tolerances, so the weight of each generally between 21.5 ~ 23 grams.
- Osmium is very difficult to process, to be made into a regular shape, and grinding machine processing, wire cutting processing are difficult.
- Osmium is almost the only metal that remains brittle even near its melting point, it can not be thermally processed or deformed under almost any circumstances, which leads to unusually difficult processing, osmium processing products are very rare.
- our osmium target material is made of 9995 osmium powder sintered at high temperature, the highest density of 22 or more, and then through the wire cutting, grinding machine, hand-polished from the production of a unique blue color, impressive feel, as well as a high cost-effective. Meanwhile, our osmium cubes have been upgraded to the fourth generation, with higher density than before, as well as better surface quality and mirror effect.
- osmium is a heavy platinum precious metal, is also a very low content of stable elements in the earth's crust, rarer than iridium, the world's annual production is less than a ton, very rare, and osmium metal is basically sold in powder form, powder metallurgy to get the osmium block has been quite small, and melting to get the osmium close to the theoretical density of osmium is even fewer and fewer.
- osmium is a fairly dense monomers in nature, the density is as high as 22.59 g/cm3, the melting point is very high, up to 3045 ° C. In nature, osmium is usually sold in the form of osmium, and the density of osmium is very high. Osmium in nature usually in the form of pure metals or alloys exist, and osmium is basically in the form of copper and nickel mining and refining process by-products and production.
- Osmium powder has a grayish-blue color, and osmium lumps have a deep, fascinating blue color. Although there are places on the Internet that the blue color of osmium comes from osmium dioxide, but the owner did not find any evidence to prove that the blue color of osmium comes from osmium dioxide, but rather the fresh fracture surface of osmium is also blue, even if it is cut in an argon environment is blue, so the owner believes that the blue color is the true color of osmium . Osmium in its dense state is stable at room temperature, osmium metal is hard and brittle and is easily broken into powder.
