High purity silica refers to silicon dioxide (SiO2) with an exceptionally high level of purity, typically exceeding 99.9%. It is obtained through various refining processes to eliminate impurities and ensure its suitability for demanding applications across different industries. Characteristics and Applications Semiconductor Manufacturing: High purity silica serves as a crucial material in the production of semiconductor devices. It is used in the fabrication of silicon wafers, where its purity ensures minimal impurities that could negatively impact the electrical properties of the semiconductor. Optical Components: Silica with high purity is utilized in the manufacturing of optical fibers, lenses, and other optical components. Its transparency and low optical absorption make it ideal for transmitting light with minimal loss, essential for telecommunications, medical devices, and laser systems. Advanced Ceramics: High purity silica is a fundamental component in the production of advanced ceramic materials such as silica glass and silicon nitride ceramics. These materials find applications in industries ranging from aerospace and defense to electronics and biomedical. Pharmaceuticals and Cosmetics: Silica with high purity is used as an excipient in pharmaceuticals and cosmetics. It serves various functions including as a flow agent, desiccant, and viscosity modifier in formulations. Chemical Synthesis: High purity silica acts as a catalyst or catalyst support in various chemical reactions and processes. Its high surface area and uniform pore structure make it suitable for applications in catalysis, chromatography, and adsorption. Construction Materials: High purity silica is incorporated into construction materials such as concrete, mortar, and grouts to improve strength, durability, and resistance to environmental factors. It also contributes to the production of high-performance coatings and sealants. Environmental Remediation: Silica with high purity is used in environmental remediation applications such as water filtration and soil stabilization. Its inert nature and high surface area enable efficient removal of contaminants from water and soil.
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.

---------Description--------- ! We provide installation work and operational training for all of our equipment! Fixed Crushing-Screening & Sand Washing plant is another type of mining equipment solution that is targeted for hard stone types with sandy physical composition like Riverstone, where sand separates from the stone after the crushing process and neeeded to be washed away. After completion of crushing process, the product is sorted into necessary fractions and the smallest size product is sent to the helix/screw sand washer and after to the final stockpile conveyor belt. The process of washing that begins at the vibrating screen with the use of water pump tubes at each layer, continues at the sand washer, therefore sending both sandy water and sorted product to the helix washer. Depending of initial stone size, jaw crusher can be added at the primary stage. In our case, the stone is smaller than 400 mm, therefore we use secondary impact crusher and vertical shaft impact crusher. Crushing-Screening Line consists of: Secondary Impact Crusher 1120 x 1500 mm Vertical Shaft Impact Crusher 900 mm Inclined Vibrating Screen 2000 x 6000 mm (2 pcs) 600 x 6000 mm helix sand washer (2 pcs) Main, stockpile, feedback conveyor belts All intersystem electrical cables Control panel with control system Feel Free To Contact Us For Any Additional Information!
