What's the difference between modern new materials and old materials?
The new material industry covers a wide range, including rare earth, magnetic materials, diamond materials, new energy materials, special ceramic materials, optoelectronics, information materials, intelligent materials, biomedical materials and so on. Except for a few, these industries have resource monopoly. Most of them are competitive industries. Although the competition is fierce, due to the high technical content of these industries, the added value of products is great. Therefore, the profitability of most enterprises is relatively high.
Development Trend of New Materials Industry in China
China has become a big producer and consumer of new materials. The output of basic materials such as steel, important nonferrous metals, main building materials and synthetic fibers ranks first in the world. The industrial added value of all industrial materials is about149.64 billion yuan, accounting for about 14.6% of China's GDP. Wang Qi 'an, director of the Materials Division of the High-tech Development and Industrialization Department of the Ministry of Science and Technology, pointed out that there are still many problems in China's new materials industry, such as high consumption of resources and energy in the production process, a big gap between the development of high-performance materials and their varieties and the world's advanced level, advanced preparation and processing technology, characterization and application of material properties, few varieties with independent intellectual property rights, and most key materials with high technical content and high added value rely on imports. Therefore, the development of new materials industry in China needs to be accelerated.
