TIO2 ANATASE - Reference Information
| introduction | titanium pentoxide has metallic luster. Oxygen content 62.3% ~ 64.3% (atoms). The orthorhombic crystal system structure, the lattice constant α = 0.3747nm. Density 4.29g/cm3. Melting point 2180 ℃. It is a material for vacuum coating. |
| application | nanocrystalline titanium oxide electrode can be used in photovoltaic applications. It plays an important role as a photocatalyst under visible light radiation. Treated titanium oxide nanotubes play an important role in the development of nano-sized hydroxyapatite. It is also used as a catalyst. |
| corrosion resistance | titanium pentoxide corrosion resistance: titanium is a very active metal, its equilibrium potential is very low, and its thermodynamic corrosion tendency in the medium is large. But in fact, titanium is very stable in many media, such as titanium is corrosion-resistant in oxidizing, neutral and weak reducing media. This is because titanium and oxygen have a great affinity. In the air or oxygen-containing medium, the surface of titanium generates a dense, strong adhesion, and inert oxide film to protect the titanium matrix from corrosion. It will heal or regenerate quickly even due to mechanical wear. This indicates that titanium is a metal with a strong tendency to passivate. Titanium oxide film with medium temperature below 315 ℃ always maintains this characteristic. In order to improve the corrosion resistance of titanium, surface treatment technologies such as oxidation, electroplating, plasma spraying, ion nitriding, ion implantation and laser treatment have been developed to enhance the protective effect of titanium oxide film and obtain the desired corrosion resistance effect. In order to meet the needs of metal materials in the production of sulfuric acid, hydrochloric acid, methylamine solution, high temperature wet chlorine and high temperature chloride, a series of corrosion-resistant titanium alloys such as titanium-molybdenum, titanium-palladium, titanium-molybdenum-nickel have been developed. Titanium castings use titanium -32 molybdenum alloy, and titanium -0.3 molybdenum -0.8 nickel alloy or titanium -0.2 palladium alloy is used locally in environments where crevice corrosion or pitting corrosion often occurs, and good results have been obtained. |
