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.
Ruthenium is a silver-white metal with a density of 12.3, a melting point of 2310 and a boiling point of 3900. Ruthenium is not vivid in chemical properties, insoluble in acid and acid, soluble in molten alkali, carbonate, etc. React with fluorine, chlorine, etc.
Nano-zirconium powder is prepared by vapor phase CVD method. It has high purity, high sphericity, low bulk density, uniform particle size, narrow distribution range, large specific surface area, high surface activity, spherical shape, good dispersion, high oxidation temperature and luster, so its appearance is similar to steel.
Zirconium is a chemical element whose chemical symbol is Zr, which has an atomic number of 40 and is a high melting point metal that is light gray. The density is 6.49 g/cm 3 . The temperature of 1852 ± 2.001 ° C, the boiling point of 4377 ° C. The valence price is +2, +3 and +4. The first ionization energy is 6.84 eV.
Zirconium silicide is a silicide, gray square crystal powder. Metal zirconium and silicon powder are used as raw materials.
The zirconium hydride chemical formula ZrH2 has a density of 5.6 g/cm3 and decomposes before melting to form heat -39.7 kcal/mol. It is prepared in the same manner as titanium hydride, and the temperature of the hydrogenation reaction is often carried out at 900 °C.
