Chromium oxide (Cr2O3) has broad application prospects. The development of the industry is favored by the improvement of standards and the expansion of applications.
Chromium oxide, also known as chromium trioxide, is an inorganic compound with the chemical formula Cr2O3. It appears as a green crystalline powder and is insoluble in water, acid and alkali solutions, but soluble in hot alkali metal bromate solutions. Chromium oxide has the advantages of high melting point, high hardness, excellent oxidation resistance, strong corrosion resistance, strong wear resistance, and good high temperature stability. It has broad development prospects in the fields of metallurgy, coatings, ceramics, chemicals, etc.
There are various production methods for chromium oxide, mainly including the redox method, which uses chromates (such as sodium chromate, potassium chromate, etc.) as raw materials and reacts with reducing agents such as ferrous sulfate and ferrous sulfate to generate chromium oxide; Thermal decomposition method is a method that uses chromate as raw material and heats it to high temperature to decompose it to generate chromium oxide; chemical vapor deposition method is a method that uses metal chromium and oxygen as raw materials and generates chromium oxide under high temperature reaction; wet chemistry The method uses chromic anhydride solution as raw material, hydrolyzes it to form a precipitate, and then produces chromium oxide through drying, roasting and other processes. Among them, the redox method and the thermal decomposition method are the commonly used production methods of chromium oxide.
According to the “China Chromium Oxide (Cr2O3) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research CenterIt shows that chromium oxide has a wide range of applications. In the metallurgical field, it is mainly used in the production of metallic chromium and ferrochromium alloys; in the chemical industry, it can be used as a catalyst carrier or additive for automobile exhaust treatment and organic chemical synthesis; in ceramics In the field of coatings, it can be used as a colorant in the coloring of porcelain and ceramic tile products, and as a key raw material for the production of ceramic glazes; in the field of coatings, it can be used as a type of environmentally friendly pigment for outdoor architectural decoration and protection scenes, and can also be used in outdoor architectural decoration and protection scenes. It can be used as an anti-corrosion and wear-resistant coating in automobile, machinery, and electronic device manufacturing scenarios.
With the continuous deepening of research, the application fields of chromium oxide are constantly expanding, and it has good application prospects in the fields of photocatalysis, photovoltaics, photolysis of water and hydrogen production. While the market is developing rapidly, domestic chromium oxide-related industry standards are constantly being improved. For example, in May 2023, the Ministry of Industry and Information Technology approved and released “Chromium Oxide Powder for Thermal Spraying” YS/T1591-2023. In the future, under the implementation of standards, the domestic chromium oxide industry will shift from rapid development to high-quality development.
Industry analysts said that chromium oxide is a type of organic chemical product with excellent performance and wide application. The development of the domestic industry is favored by the continuous development and expansion of downstream application fields and the continuous establishment and improvement of relevant industry standards, showing good development prospects. In my country, the main chromium oxide production companies include Jinzhou Vanadium, Netchier New Materials, Bohong Chemical Technology, Gansu Jinshi Chemical, Zhonglan Yima Chromium Chemical, Luoyang Zhengjie New Materials, Anjian Leather Chemical, Liaoning Tianxi Metal, Qinghai Xinghuo Industrial, etc.
