China will establish a variety of ore strategic reserves
China is currently the world's largest consumer of steel, copper and aluminum. Take aluminum as an example. With the acceleration of urbanization and industrialization in China in the next few years, the consumption of electrolytic aluminum in China will continue to grow. Relevant departments expect that from 2005 to 2007, aluminum for construction will increase by 8% to 15%, reaching 2.43 million tons, 2.72 million tons and 2.94 million tons respectively. It is reported that China is currently the largest consumer of primary aluminum after the United States.
In the first quarter of this year, China’s economy grew by 10.2% over the same period of last year, ranking first in the world’s major economies. As China is entering a new phase of industrialization, in order to ensure growth and stability, China must possess sufficient critical resources.
It is reported that China has proposed to establish strategic oil reserves this year. The government also urges the world's second largest aluminum producer, China Aluminum Corporation, to seek overseas resources to ensure that domestic demand is met.
The Ministry of Land and Resources also stated that as part of the “Eleventh Five-Year Planâ€, the government will jointly establish ore reserves. It will intensify the exploration of domestic mineral resources and strive to increase the reserve of iron ore by 5 billion tons, copper by 20 million tons, and bauxite by 200 million tons by 2010. On the other hand, the state-owned assets department also plans to add 4.5 billion to 5 billion tons of oil reserves and 100 billion tons of coal resources.
Oxide powder for thermal spray refers to a type of powder material that is used in thermal spray processes. Thermal spray is a coating technique where a material in powder form is heated and propelled onto a substrate, forming a coating.
Oxide powders are commonly used in thermal spray applications due to their high melting points, excellent wear resistance, and thermal insulation properties. They can be used to create protective coatings on various surfaces, such as metals, ceramics, and plastics.
Some common types of oxide powders used in thermal spray include:
1. Aluminum oxide (Al2O3): This oxide powder is widely used for its high hardness, wear resistance, and thermal insulation properties. It is commonly used for coating applications in industries such as aerospace, automotive, and electronics.
2. Zirconium oxide (ZrO2): Zirconium oxide powder is known for its high melting point and excellent thermal barrier properties. It is often used in thermal spray coatings for gas turbine engine components, where thermal insulation is critical.
3. Chromium oxide (Cr2O3): Chromium oxide powder is used for its high hardness, corrosion resistance, and wear resistance. It is commonly used in applications where high temperature and abrasive wear resistance are required.
4. Titanium oxide (TiO2): Titanium oxide powder is known for its high refractive index and excellent UV resistance. It is often used in thermal spray coatings for optical and decorative applications.
These oxide powders can be applied using various thermal spray techniques, such as flame spraying, plasma spraying, or high-velocity oxy-fuel (HVOF) spraying. The choice of oxide powder and thermal spray technique depends on the specific application requirements and desired coating properties.
