Cupric oxide wire is used in the production of superconducting materials and as a precursor for copper-based catalysts. Due to its excellent electrical conductivity and high-temperature resistance, it is commonly applied in the manufacturing of electronic ceramics, sensors, and semiconductors. The wire form is particularly utilized in special wiring for harsh environments, such as thermal power systems or devices requiring corrosion resistance. It is employed in the synthesis of nanomaterials and in the development of antimicrobial coatings for medical devices and textiles. Its suitable surface properties make it ideal for gas sensor research in nanotechnology. Also utilized in the glass and enamel industries to impart color and improve stability.
