Iron Oxide red is divided into artificial iron oxide red and natural iron oxide red. Natural iron oxide red is dark red or red amorphous powder, while the crystal structure and physical properties of artificial iron oxide red are different due to different preparation methods and operating conditions. The colors are red and purple. The production methods of iron oxide red mainly include iron oxide black method, direct oxidation method, precipitation method, hydrothermal method, calcination method - ferrous sulfate + soda ash, etc.
Iron oxide red is insoluble in water and all alkalis, but gradually soluble in strong acids at high temperatures. It has excellent light resistance, high temperature resistance, pollution resistance, atmospheric resistance, weather resistance, etc. It is mainly used in building materials, coatings, plastics, advanced fine grinding materials and other fields. China's iron oxide red industry has experienced three rounds of development, from the initial stage of the founding of new China to the mature stage of the industry in the 21st century.
In recent years, China's iron oxide red production capacity has been expanding, while the capacity utilization rate has gradually decreased, and the market is in a state of overcapacity. According to the data, China's domestic capacity will reach 351000 tons in 2019, a year-on-year increase of 1.74% compared with 345000 tons in 2018, and the capacity utilization rate will be 70.20%
Affected by the overall economic environment, the economic growth of China's iron oxide red industry has slowed down, but the output remains relatively stable. According to the data, the output of iron oxide red in China reached 246000 tons in 2019 and 244000 tons in 2020, a year-on-year decrease of 1%.
In recent years, the demand of iron oxide red industry in China has been fluctuating. According to the data, the demand for iron oxide red in China in 2019 was 222300 tons, an increase of 4.32% over 2018; In 2020, China's demand for iron oxide was 208100 tons, a year-on-year decrease of 6.39%.
From the perspective of the downstream consumption market of iron oxide red in China, the market share in the field of coatings and paints in China will be the largest in 2020, accounting for 45.3%; Followed by the construction sector, accounting for 28.5% of the market; The market share of rubber and plastics reached 16.2%.
The paint industry is the largest application field of iron oxide red in China. In recent years, the output of paint in China has been increasing, which has also promoted the development of iron oxide red industry in China. According to the data, China's paint output in 2020 was 24.591 million tons, an increase of 0.83% over the same period in 2019.
