Crystalline silicon micro powder (SiO2) is a widely used inorganic non-metallic material, which has excellent dielectric properties, low thermal expansion coefficient, low thermal conductivity, and corrosion resistance. Meanwhile, high-quality silicon micro powder has become one of the important and key raw materials in the field of new technology due to its excellent physical properties, extremely high chemical stability, and unique optical properties.
With the implementation of the national "the Belt and Road" and "Made in China 2025" strategies, high-tech silicon micro powder materials, as the basic industry of modern electronic information industry, have entered the track of rapid development.
At present, the development and innovation of the silicon powder industry should pay attention to the following trends:
(1) Production is highly modernized.
Due to the increasing requirements for the purity, particle size, and shape of silicon micro powder in the microelectronics industry, the development of dust-free production processes and specialized equipment is particularly important. At the same time, online monitoring and control must be carried out to ensure the high quality and stability of products.
(2) The pace of technological innovation is accelerating.
Due to the particularity and diversity of high-tech silicon micro powder materials, simply improving traditional processes and equipment is far from enough. With the rapid development of modern processing technology, cutting-edge technologies such as plasma technology, radio frequency technology, ultrasound technology, vacuum technology, and optoelectronic technology should be integrated and adopted as soon as possible.
(3) Developed industrial countries around the world are constantly strengthening their protection of intellectual property rights.
The core parts of high-tech silicon micro powder production plants abroad are almost entirely operated in a closed manner, and outsiders are not allowed to approach. In negotiating technology trade projects, core technologies are not transferred to external parties. Japan has always kept confidential the parameters of high-tech silicon micro powder exported to China, and Germany even restricts the export of high-tech silicon micro powder as a strategic material.
(4) The independent innovation of technology must seek new development space.
With the acceleration of technological innovation, the technical indicators of some products have reached their limits. Scale, low cost, high purity, multiple varieties, and functionalization are still the development trends of high-tech silica micro powders. In addition, the synthesis technology, intelligent technology, and micro nano technology of high-tech silicon micro powder will inevitably reach a new level. Therefore, interdisciplinary innovation efforts must be continuously increased.
