Copper oxide

Copper oxide is an inorganic compound with the chemical formula CuO, and it is a black copper oxide. It is slightly amphoteric, has some hygroscopic properties, is insoluble in water and ethanol, but easily dissolves in acids. Copper oxide decomposes to release oxygen at high temperatures and is thermally stable. Its appearance is a black or brown-black powder with a density of 6.31 g/cm³. Copper oxide has various applications. It is mainly used in the manufacture of artificial silk, ceramics, glazes and enamels, batteries, petroleum desulfurizers, and pesticides. Additionally, copper oxide is used in hydrogen production and as a catalyst, as well as in the manufacture of green glass.

    Product Features:

    1. Copper oxide can give optical glass a variety of colors, such as blue, green, red, etc., providing more choices and possibilities for the design and manufacture of optical glass. This rich color presentation gives copper oxide a significant advantage in the manufacture of artistic glass, colored glass, and other optical glass products. At the same time, the composition of copper oxide can blend well with glass, resulting in colors that have high stability and are not easily affected by external environmental factors (such as temperature, humidity, etc.), ensuring the color quality of optical glass during long-term use.

    2. In certain photochromic optical glasses, copper oxide can work synergistically with other substances (such as silver halides) to achieve photochromic functions. When exposed to strong light, silver halides undergo decomposition reactions, producing silver atoms and halogen ions, with copper oxide acting as a catalyst to accelerate the decomposition of silver halides and help form stable silver clusters or compounds, causing the glass color to darken, thus blocking strong light. When the light weakens or disappears, silver and halogen recombine into silver halides under the catalytic action of copper oxide, and the glass color gradually lightens. This photochromic characteristic allows optical glass to automatically adjust its color depth according to changes in light intensity, which can be applied to photochromic glasses, protecting the eyes from strong light while maintaining good visual effects under different lighting conditions.

    3. Copper oxide can absorb ultraviolet and some blue light, reducing the harm of these harmful rays to the human eye, while also improving the optical purity of optical glass, making the light passing through the glass clearer and purer. This is of great significance for optical instruments, lenses, and other products that require high transparency and good optical performance.

    4. Adding an appropriate amount of copper oxide can change the refractive index and dispersion properties of optical glass, making it more suitable for the design requirements of specific optical systems. This helps improve the imaging quality and precision of optical systems, giving optical coatings greater advantages in the manufacture of high-precision optical components.

    5. Copper oxide is used as a polishing agent for optical glass to improve the smoothness and transparency of the optical glass surface. In addition, copper oxide can also be used in optical coatings in combination with other materials to form optical films with specific functions, such as anti-reflective films and high-reflective films, to meet the needs of different application fields.
