titanium
physical features
The density of titanium is 4.506-4.5 16 g/cm3 (20℃), which is higher than that of aluminum and lower than that of iron, copper and nickel. But the specific strength is the first among metals, three times that of stainless steel and 1.3 times that of aluminum alloy. Melting point 1668 4℃, latent heat of melting 3.7-5.0 kcal/g atom, boiling point 3260 20℃, latent heat of vaporization102.5-12.5 kcal/g atom, critical temperature 4350℃, and critical temperature. Thermal and electrical conductivity of titanium is poor, similar to or slightly lower than that of stainless steel. Titanium has superconductivity. The superconducting critical temperature of pure titanium is 0.38-0.4K At 25℃, the heat capacity of titanium is 0. 126 kcal/g atomic degree, the enthalpy is 1 149 kcal/g atomic degree, and the entropy is 7.33 kcal/g atomic degree. Titanium has plasticity, the elongation of high-purity titanium can reach 50-60%, and the area shrinkage can reach 70-80%, but its strength is low, so it is not suitable for structural materials. The existence of impurities in titanium has a great influence on its mechanical properties, especially interstitial impurities (oxygen, nitrogen and carbon) can greatly improve the strength of titanium and significantly reduce its plasticity. The good mechanical properties of titanium as a structural material are achieved by strictly controlling the appropriate impurity content and adding alloying elements.
chemical property
Titanium can react with many elements and compounds at high temperature. Various elements can be divided into four categories according to the different reactions with titanium: the first category: halogen and oxygen group elements form valence bonds and ionic bonds with titanium; The second type: transition elements, hydrogen, beryllium, boron, carbon and nitrogen react with titanium to form intermetallic compounds and finite solid solutions; The third type: zirconium, hafnium, vanadium, chromium and scandium react with titanium to form infinite solid solution; The fourth category: inert gases, alkali metals, alkaline earth metals, rare earth elements (except scandium), actinides, thorium, etc. Does not react with titanium or basically does not react.
nickel
physical features
Nickel has the characteristics of good mechanical strength and ductility, high temperature resistance and no oxidation in air. Nickel is a silvery white metal. Melting point 1726K, boiling point 3005K and density 8.902g/cm3.
chemical property
At room temperature, in humid air, a dense oxide film is formed on the surface, which can prevent the bulk metal from further oxidation. The corrosion of nickel by hydrochloric acid, sulfuric acid, organic acid and alkaline solution is very slow. Nickel dissolves slowly in dilute nitric acid. Strong nitric acid can passivate the surface of nickel and has corrosion resistance. Nickel, like platinum and palladium, can absorb a lot of hydrogen in the passivation process, and the smaller the particles, the greater the absorption. The important salts of nickel are nickel sulfate and nickel chloride. Similar to iron and cobalt, it is stable to water and air at room temperature and can resist alkaline corrosion, so nickel crucible can be used to melt alkaline substances in the laboratory. Nickel can be dissolved in dilute acid. Unlike iron, cobalt and nickel react strongly with concentrated nitric acid, but slowly with dilute nitric acid.
