Product Description

Electronic grade silica sol is a highly dispersed liquid of nano-scale silicon dioxide particles in water or solvent. It has extremely high purity and is usually used to meet the needs of high-tech fields such as semiconductor precision polishing CMP (chemical mechanical polishing) and the solar energy industry. This silica sol has extremely high purity. Our company can achieve greater than 99.999% or even higher. Its particle morphology, concentration, dispersion medium, pH value, etc. can be adjusted according to specific needs. Due to its excellent performance, electronic grade silica sol is widely used in chip manufacturing, solar silicon wafer crucibles, aerogels, metal/ceramic processing, inks, coatings, textiles, batteries, biomedicine and other fields.

Electronic grade silica sol Our company mainly uses the sol-gel method. Currently mainly used in:
1. Semiconductor manufacturing:
Electronic grade silica sol is used as a key material in the semiconductor manufacturing process, especially in chip packaging, polishing and cleaning processes. Due to its high purity and good dispersibility, silica sol can effectively remove surface impurities and improve the performance and reliability of semiconductor devices.
2. Optical devices:
In the manufacture of optical devices, electronic grade silica sol can be used as a polishing and cleaning agent to remove tiny scratches and contaminants on the surface of optical components and improve the transmittance and clarity of optical devices.
Liquid crystal display manufacturing:
In the manufacturing process of liquid crystal displays, electronic grade silica sol is used to prepare high-quality insulating layers and transparent conductive layers to ensure that the display has good display effect and stability.
3. Solar cell manufacturing:
In solar cell manufacturing, electronic grade silica sol is used to prepare the surface coating of solar panels to improve their anti-reflection and light absorption efficiency, thereby improving the photoelectric conversion efficiency of solar cells.
4. Microelectronic packaging:
Electronic grade silica sol is used as a filling material in microelectronic packaging, which can fill the tiny gap between the chip and the packaging substrate, provide stable mechanical support and electrical isolation, and prevent the intrusion of moisture and pollutants.
5. Catalyst carrier:
The high specific surface area and adjustable pore size of electronic grade silica sol make it an ideal material for catalyst carriers. By loading different catalysts, composite materials with specific catalytic properties can be prepared for various chemical reactions.
6. Coatings and inks:
In coatings and inks, electronic grade silica sol is used as an additive to improve the dispersion and stability of coatings, and improve the hardness and wear resistance of coatings. At the same time, silica sol can also be used to prepare functional coatings, such as self-cleaning coatings, anti-fog coatings, etc.
7. Other fields:
Electronic-grade silica sol can also be used to prepare high-performance ceramics, glass and other materials, as well as biosensors, medical devices and other biomedical applications.
In short, electronic-grade silica sol has shown broad application prospects in many fields with its high purity, high stability and good dispersibility. With the advancement of science and technology and the growth of demand, the use of electronic-grade silica sol will be further expanded.
