Appication of Chrome Oxide Green Cr2O3 Chromium Oxide
1. Lead chrome green is the main coloring pigment in the paint industry, and most of the green paints are formulated with this pigment. In addition, it is also used in paints and plastics. Its application range is very similar to that of lead chrome yellow. Due to the presence of chrome yellow in the composition, attention should be paid to the toxicity of lead. Lead chrome green contains iron blue and the oxidant lead chromate, so when the dust encounters sparks, there is a possibility of spontaneous combustion, so be careful when drying and crushing. After burning, the lead chrome green completely loses the characteristics of green pigment and turns into a dark brownish-yellow substance. In addition, when making nitro paint, the rolling process is not directly rolled with lead chrome green, but the process of grinding with lead chrome green to prevent burning during rolling.
2. Used in metallurgy, also used as ceramics, refractory materials, raw materials for pigment industry and organic synthesis catalyst.
3. Used as analytical reagent, catalyst.
4. It is used as a coloring, abrasion resistance and corrosion resistance filler for adhesives and sealants. It can also be used as a colorant for enamel, ceramics, artificial leather, and building materials; a catalyst for organic chemical synthesis; a light-fast coating and a special ink for printing banknotes.
5. It is used as a colorant in cosmetics, mainly used in eye cosmetics, but not in oral and lip cosmetics, and is not recommended for facial cosmetics and nail polish.
6. Chromium trioxide is one of the main components of the silver-plated layer dipping solution. The newly prepared chromium dioxide is an important raw material for preparing chromium fluoride and chromium bromide.

FAQ
Q1
Is chromium oxide green harmful to human body?
Answer: Chromium oxide green itself is relatively safe for the human body under normal use conditions. However, prolonged exposure to large amounts or inhalation of its dust may cause irritation to the respiratory tract and skin. Therefore, when handling chromium oxide green, you should wear appropriate protective equipment and ensure that the operating environment is well ventilated.
Q2
How to store chromium oxide green?
Answer: Chromium oxide green should be stored in a dry, ventilated, and cool place away from direct sunlight and high temperatures. At the same time, it should be stored separately from acids, alkaline substances, etc. to prevent chemical reactions.
Q3
What are the applications of chromium oxide green in the coating industry?
Answer: In the coatings industry, chromium oxide green is used as a green pigment that provides bright color and good durability. It can be mixed with other pigments to create different shades of paint to meet different decorative and protective needs.
Q4
What are the advantages of chromium oxide green over other green pigments?
Answer: Compared with other green pigments, chromium oxide green has higher color fastness and stability and is not easy to fade. In addition, it has good hiding power and dispersion, making the paint more even and durable.
Q5
What is the environmental performance of chromium oxide green?
Answer: Chromium oxide green performs well in terms of environmental performance. It does not contain harmful substances and is unlikely to produce harmful emissions during use. However, during production and processing, attention still needs to be paid to preventing the generation and emission of dust to ensure the safety and hygiene of the working environment.
