The temperature of 1852 ± 2.001 ° C, the boiling point of 4377 ° C. The valence price is +2, +3 and +4. The first ionizatio…
Yttrium (element symbol Y) is a heavy rare earth metal element. Yttrium is an important heavy rare earth metal because its physical and chemical properties are similar to those of other rare earth metals and often coexist with rare earth minerals of other rare earth metals. Yttrium metal has many ap…
The vanadium powder is a silvery white metal. Vanadium is a high melting point rare metal with a density of 5.96, a melting point of 1890 ° C, a boiling point of 3380 ° C, resistance, and is brittle in heating, and vanadium containing oxygen and nitrogen is also brittle. Vanadium is a poor conductor…
Tungsten is a gray ferrous metal with metallic luster (body-centered cubic crystallization). Melting point 3400℃. Boiling point 5555℃. The hardness of tungsten is the hardest in metal. The hardness of sintered tungsten bars is 200-250, and that of rotary hammer is 350-400. Mixed acids dissolved in n…
Among the metal elements, the specific strength of titanium is high. It is a high strength but low quality metal with very good ductility (especially in an oxygen free environment). The surface of titanium is a silvery white metallic luster. Its melting point is quite high (more than 1,649 degrees C…
Titanium silicide is used in the semiconductor industry. It is typically grown by means of salicide technology over silicon and polysilicon lines to reduce the sheet resistance of local transistors connections. In the microelectronic industry it is typically used in the C54 phase.
Titanium silicide…
Titanium nitride powders are usually yellowish brown, ultrafine TiN powders are black, and TiN crystals are golden yellow. TiN has a melting point of 2950 C, a density of 5.43-5.44g/cm3, a Mohr hardness of 8-9 and good thermal shock resistance. The melting point of TiN is higher than that of most tr…
There are two main crystalline forms of nano-titanium dioxide: anatase and rutile. Rutile titanium dioxide is more stable and dense than anatase titanium dioxide. It has higher hardness, density, dielectric constant and refractive index, and its covering power and coloring power are also higher. The…
Titanium carbide is a typical transition metal carbide. Its bond type is composed of ionic bonds, covalent bonds and metal bonds in the same crystal structure, so titanium carbide has many unique properties. The structure of the crystal determines the basic characteristics of titanium carbide with h…
The sintering of titanium alloy powder is usually a solid phase diffusion method. When the titanium alloy was prepared by the mixed element method, it was found that the alloying elements in the titanium alloy showed a transient liquid phase during sintering or provided a diffusion channel to promot…
