Chromium oxide is a material with a variety of uses. Its physical and chemical properties are widely used in many industries and fields. Here are some of the main application areas:
Ceramics and Glass Industry: Chromium oxide is mainly used as a colourant in the ceramics and glass industry. It can give products a vivid green or blue colour and enhance their heat resistance and chemical stability. In glass, chromium oxide can also increase UV-blocking capabilities.
Electronics and photovoltaic industry: Chromium oxide plays an important role in the electronics and photovoltaic industry. It can be used as an absorber layer in solar cells to improve the photoelectric conversion efficiency of the cell. In addition, chromium oxide can also be used to manufacture optoelectronic devices such as photodiodes and phototransistors.
Catalysts and sensors: Chromium oxide is a good catalyst and sensor material. In chemical reactions, it can promote the oxidation-reduction reaction to achieve the transformation of chemical substances. Additionally, chromium oxide can be used to create chemical sensors whose colour changes can be used to detect the presence of specific chemicals.
Wear-resistant coating: Due to its excellent wear-resistant properties, chromium oxide is widely used to manufacture wear-resistant coatings. These coatings can be applied to various material surfaces, such as metals, plastics and ceramics, to improve their resistance to wear.
Optical coatings: Chromium oxide has high light transmission and low reflectivity, making it an ideal material in optical coatings. It can be used to produce a variety of optical devices such as mirrors, prisms and window materials.
High-temperature coating: Chromium oxide has excellent high-temperature resistance and can make high-temperature coatings. These coatings can be applied to high-temperature equipment, such as rocket engines and gas turbines, to improve their high-temperature protection properties.
Electrochemical industry: Chromium oxide can be used as an electrode material in electrochemistry. With good electrical conductivity and chemical stability, chromium oxide exhibits good properties in applications such as batteries and fuel cells.
Coatings and Pigments Industry: Chromium oxide can make various coatings and pigments. These products can be used for decoration, artistic creation and product appearance treatment.
Medical and biological industries: Chromium oxide also has certain applications in the medical and biological fields. For example, some chromium oxide forms can be used as drug carriers for drug delivery and as biosensors for disease detection.
Water and wastewater treatment: Chromium oxide also has certain applications in the environmental and wastewater treatment fields. It can serve as a catalyst or adsorbent to treat harmful substances in water, thereby purifying water quality.
