1. Polishing materials
In the manufacturing process of electronic components, the polishing process is particularly critical. Electronic grade silica sol is often used as one of the important components of polishing liquid and is widely used in the smoothing of silicon wafers, glass and other materials. Its ultra-fine silicon particles can penetrate into tiny surface defects to achieve efficient removal and smoothing effects. By using electronic grade silica sol, the surface roughness of the silicon wafer produced is significantly reduced, thus providing a good foundation for subsequent processes such as doping, oxidation and etching.
2. Dispersant for cathode ray tube coating
The application of electronic grade silica sol in cathode ray tube (CRT) coating is equally important. As a dispersant for coating, this material can effectively increase the fluidity and dispersibility of the coating and ensure that the coating is evenly distributed inside the cathode ray tube. This not only improves the image quality of the cathode ray tube, but also enhances its durability and service life. Electronic grade silica sol can also exert excellent covering power, allowing the cathode ray tube to maintain excellent image restoration capabilities under different working conditions.
3. Electronic packaging
Modern electronic packaging technology requires materials to have good thermal conductivity, pressure resistance and chemical stability. Electronic grade silica sol, as an excellent filling material, has these characteristics. It can fully fill the gaps between electronic components during the packaging process, improve the tightness of the packaging, and prevent the impact of the external environment on the components. In addition, based on its good insulation, electronic grade silica sol can also maintain stable performance under high frequency and high temperature conditions, providing a guarantee for the reliability of electronic products.
With the continuous innovation of electronic products and technological advancement, the market demand for electronic grade silica sol is also growing continuously. According to statistics from market research institutions, it is expected that the global electronic grade silica sol market will maintain a rapid growth trend in the next few years.
