Zirconium is a rare metal, with amazing corrosion resistance, extremely high melting point, ultra-high hardness and strength and other characteristics, is widely used in aerospace, military, nuclear reaction, atomic energy fields.
Titanium is best known for its corrosion resistance, which is almost as good as platinum. Titanium is not corroded by dilute sulfuric acid, dilute hydrochloric acid, chlorine gas, chlorine solution and most organic acids, but it can still be dissolved by concentrated acid.
Inconel 718 is a precipitation hardening nickel-chromium-iron alloy containing niobium and molybdenum. It has high strength, good toughness and corrosion resistance in high and low temperature environment at 700 ~C. The state of supply may be solid solution treatment or precipitation hardening.
Osmium, 6 cycles Ⅷ group element periodic table, a member of platinum group metals. Element symbol Os, atomic number 76, relative atomic mass 190.2, belongs to heavy platinum group metal, which is the densest metal known at present.
Iridium: belongs to the periodic table Ⅷ transition element, atomic number 77, atomic number 192. 2, face-centered cubic lattice, is a rare precious metal material. Two new elements, osmium and iridium, were found in the black powder left at the bottom of the vessel when the crude platinum was dissolved in royal water. Iridium content in the earth's crust is one part in ten million and is often dispersed in alluvial and sandy deposits with platinum series elements.
Titanium carbide chemical formula TiC. Steel gray crystal with metallic luster. It has thermal conductivity and electrical conductivity, and its electrical conductivity decreases with increasing temperature, so it exhibits metallic properties. It is a very hard, high melting point compound with hardness second only to diamond and a microhardness of 2850 kg/mm. It belongs to NaCl type tetragonal system, lattice constant a=4.173×10cm, melting point 3150°C, boiling point 4820°C, relative density 4.9.
Nano- sized iron oxide has good weather resistance, light resistance, magnetic properties and good absorption and shielding effect on ultraviolet light.
Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields because of their high strength, good corrosion resistance and high heat resistance.
Refining of osmium refers to the process of refining impurities in the crude crucible to produce pure rhodium in the platinum group metal refining process. It is composed of two stages of purification and purification of the absorbing liquid and preparation of the metal ruthenium, and the former is often more important.
