Features and Applications
High Purity: Electronic grade silica sol is produced with extremely high purity levels to minimize impurities that could adversely affect electronic components. This ensures the reliability and performance of semiconductor devices and integrated circuits.
Particle Size Control: The particle size distribution of electronic grade silica sol is tightly controlled to meet precise specifications. This uniformity is crucial for achieving consistent results in semiconductor fabrication processes such as chemical mechanical planarization (CMP) and wafer cleaning.
Surface Properties: Electronic grade silica sol is designed to have specific surface properties tailored for electronic applications. These properties may include controlled surface charge, stability, and compatibility with other process chemicals.
Polishing and Planarization: In semiconductor manufacturing, electronic grade silica sol is used in CMP slurries for polishing and planarization of silicon wafers. It helps achieve smooth and flat surfaces essential for patterning and layer deposition processes.
Dielectric Films: Electronic grade silica sol can be used to deposit thin dielectric films on semiconductor substrates through techniques such as spin coating or dip coating. These films act as insulating layers in electronic devices, providing electrical isolation between different components.
Passivation and Encapsulation: Silica sol can be employed for passivation and encapsulation of semiconductor devices to protect them from moisture, contaminants, and mechanical damage. The high purity and stability of electronic grade silica sol ensure long-term reliability and performance.
Photolithography: Electronic grade silica sol may also be utilized as a photoresist adhesion promoter or anti-reflective coating in photolithography processes. It helps enhance pattern fidelity and resolution during the fabrication of semiconductor circuits.
Wafer Cleaning: Silica sol is used in wafer cleaning processes to remove contaminants, particles, and organic residues from semiconductor surfaces. Its high purity and compatibility with other cleaning agents make it an essential component in advanced cleaning solutions.
Glass GRADE "Glass grade properties" typically refer to the specific characteristics and qualities of glass that determine its suitability for various applications. Glass comes in a wide range of types and grades, each with its own set of properties that make it suitable for different purposes.High grade silica sand manufacturer for Glass Industries serving both Float glass as well as container glass Industries. We are manufacturing around 3000 to 5000 Tons of Glass Grade Sand per month. Here are some important glass grade properties: Properties: 80 - 100 ppm 130 - 150 ppm 150 - 200 ppm 200 - 250 ppm 250 - 300 ppm 300 - 500 ppm Transparency: Glass is known for its transparency, allowing light to pass through. The level of transparency can vary based on factors such as the type of glass, its thickness, and any coatings or treatments applied to it. Hardness: Glass is a hard material, but its hardness can differ based on the specific type of glass. Some glasses are more scratch-resistant than others.

Silica gel is a desiccant and adsorbent material known for its ability to absorb moisture and maintain a dry environment. It consists of small, porous, and translucent beads of silicon dioxide (SiO2), and it is commonly found in small packets or pouches within product packaging to protect against moisture damage. Silica gel is invaluable for preventing the growth of mold, mildew, and corrosion in various products, such as electronics, leather goods, and pharmaceuticals. It is also used in industries like food packaging, where it helps extend the shelf life of products by reducing humidity and preventing moisture-related spoilage. Silica gel's exceptional moisture-absorbing properties and non-toxic nature make it a practical and widely used solution for preserving the quality and longevity of a wide range of items.
