Physical performance
In terms of physical properties, Magneli phase titanium oxide material, at room temperature has good electrical conductivity. Especially Ti4O7, is the best conductivity of a phase, the single crystal conductivity of 1500Scm-1. The bulk density is 3.15 g / cm-3-3.18 g / cm-3
Chemical properties
In the chemical properties, Magneli phase titanium oxide material, compared with the general industrial electrode materials, with high chemical stability and corrosion resistance. It is documented that the static corrosion rate of Magneli phase titanium oxide is only 0.019 g / m2 / day at 50 ° C and 42% H2SO4. On the other hand, Magneli phase titanium oxide has good electrochemical properties. Experiments show that at room temperature, the operating current control in the 5-20mA / cm2, the material can be used as a positive electrode can also be used as a negative electrode for hydrogen evolution reaction, and hydrogen evolution oxygen overpotential high, such as in 1M H2SO4, At room temperature, the oxygen current potential can be as high as 5 volts at medium current density

Applications:
Lead-acid battery applications:
1) to improve the formability of the positive electrode active material and the utilization of the active material. Since the conductive ceramic-titanium oxide (Ti4O7) can enhance the bonding force with PbO2 and maintain the pore shape and porosity during the charging and discharging process, the moldability of the positive electrode active material and the utilization ratio of the active material are improved. With a small amount of titanium oxide (Ti4O7) fiber added in the automotive flat-panel battery, you can increase the battery capacity of 15-17%.
Battery area:
Lithium battery: as a cathode instead of graphite can reduce the charge and discharge cycle of the capacitor attenuation;
Fuel cell, zinc – air battery and liquid battery: Because of its high conductivity and corrosion resistance, is very promising electrode and bipolar material;
Chemical industry:
Because of its excellent chemical stability and conductivity, can be used for chlor-alkali industry, chlorate manufacturing, dichromic acid preparation and organic synthesis;
Electric metallurgy field:
In high current density, high acid conditions are not passivated without corrosion and better than graphite and titanium, as the electrode for electrodeposited zinc, metal recovery, electrolytic manganese oxide, metal foil production and printing circuit board etching solution reuse deal with;
Electroplating area:
Because the electrolyte contains fluorine and other corrosive substances, commonly used anode is very easy to deteriorate, and the oxidation of titanium oxide electrode over-potential, corrosion resistance, wear resistance, electrode size and stability;
Environmental protection and water treatment areas:
Because of the high oxygen evolution potential of titanium oxide electrode, it is widely used in electrocatalytic degradation of organic pollutants and landfill leachate, electrochemical treatment of phenol wastewater, printing and dyeing wastewater treatment, oilfield wastewater treatment, hospital sewage treatment and Electrolysis of sea water, desalination, electrolytic water disinfection and ozone manufacturing;
