描述
- our iridium cubes, is made of purity greater than or equal to 99.95% of iridium powder as raw material, first after vacuum high temperature melting and sintering, and then cutting and polishing, and finally polished out of the production, containing pure iridium Ir ≥ 99.95%, the surface is smooth and bright, polished to a mirror, silver-white metal luster is strong.
- iridium is a brittle hard silver-white metal, is one of the rarest metals, crustal content of one billionth, much rarer than gold, iridium melting point is extremely high, up to 2466 °, iridium at high temperatures will be reacted with oxygen to generate volatile iridium dioxide IrO2, serious evaporation loss of gravity, it must be in the vacuum under the conditions of the e-beam can be smelted, the cost is very high.
- iridium corrosion resistance is extremely strong, iridium is the only one in 2000 degrees of air can maintain excellent mechanical properties without serious loss of metal, dense form of iridium inertia is extremely high, insoluble in all acids, insoluble in all acids and alkali salts at room temperature and normal pressure, iridium is also insoluble in liquid metals and a lot of corrosion of molten salts. Iridium is the most corrosion-resistant of all metals. At the same time iridium is the only crucible material for refining single crystal.
- all hand-polished, time-consuming and laborious, to achieve a mirror luster, ornamental and collectability is very strong.
- at present, this form of metal cube few people do, but the store will be a series of production, very rare, whether from the metal material or from the form, are worth collecting. It is a fine collection of elements, gifts, science teaching aids and exhibits.
