About this item

  • solid pure ruthenium, ruthenium content ≥9995, is very delicate ruthenium cubes, made from large ruthenium target material after cutting, grinding and polishing, laser engraving looks very delicate. High-power high-precision laser marking, the text is concave, non-human corrosion or wear, the text will not disappear by itself.
  • the artificial fine grinding and polishing, very smooth, basically reached the mirror surface, the effect is very good.
  • Due to the brittle ruthenium, the ductility is very poor, can not be rolled, even at high temperatures close to the melting point, ruthenium is still brittle, for machining is very difficult, so the pure ruthenium processed parts on the market are almost all powder metallurgy products, and can not be rolled to improve the density of the plate. If hot isostatic pressing is used, it is possible to produce ruthenium sheets with a density close to the theoretical density, but the cost increases dramatically and is not cost-effective.
  • the store this ruthenium processing parts using powder metallurgy of ruthenium raw materials, processing difficulty, processing process easy to crack broken, difficult to polish, very wasteful of materials, the specific gravity of 11.5 or so, although not up to the theoretical density, but the price is reasonable, it is a cost-effective collector's item.

Ruthenium Metal Elements Periodic Table

Ruthenium is a hard, brittle, light gray polyvalent rare metal element, a member of the platinum group of metals. It is one of the rarest metals in the earth's crust, with a content of only one part per billion. Ruthenium is very stable and corrosion-resistant and is resistant to hydrochloric acid, sulfuric acid, nitric acid and aqua regia at room temperature.
