CAS 1307-96-6: Cobalt oxide (CoO)

Gallium(III) oxide is used in vacuum deposition. It is useful for making semiconductor devices, gallium-alumina catalyst, gas sensors, luminescent phosphors and dielectric coatings of solar cells. It shows potential for developing deep-ultraviolet TCOs (Transparent Conductive Oxides) and transparent electrodes for ultraviolet optoelectronic devices. Recent studies report that gallium oxide can be a strong contender for power electronic devices for example, in ultrahigh-voltage power switching applications. Films made of gallium oxide have gained commercial interest owing to their gas sensitive characteristics, and glasses made with gallium oxide are the preferred optical materials for use in advanced technologies.This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

Cobalt is a transition metal with the atomic number 27. It has an oxidation state of +2 and belongs to group 8 on the periodic table. Cobalt(II) oxide (CoO) is a black solid that can be formed by heating cobalt metal at temperatures greater than 1400°C. The electrochemical impedance spectroscopy of CoO shows that it has high resistivity and good electrical conductivity, making it useful for corrosion protection. Cobalt oxide is also used as a catalyst in chemical reactions, such as oxidation and reduction, due to its redox potential. Cobalt oxide can be produced from the reaction between hydrochloric acid and zirconium oxide by electrolysis, which produces an electric current. This process can be done in two ways: either by using an electrochemical cell or by laser ablation. The latter method is more efficient because it requires less energy input than using an electrochemical cell. In addition, CoO particles are spherical in shape, have
