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.

Casting Silica
Silica sand is a primary component in the manufacturing of glass. It is a very important raw material for standard and special glasses. The chemical purity of silica sand is the principal determinant of strength, colour and clarity. It is used to produce flat glass for building and automotive uses and for container glass that stores food and beverages. It reinforces glass fibres and required for the production of fibreglass insulation. It is applied in speciality glasses that include test tubes, scientific tools, television and CRT monitors, and also in incandescent and fluorescent lamps. Calcium silicate bricks For manufacturing calcium silicate bricks, silica sand is mixed with high calcium lime with a sand to lime ratio of 10 or 20. These bricks contain good regularity, smooth faces, and sharp corners with a wide variety of strength. The durability of calcium silicate bricks is similar to concrete and is not resistant to sulphur containing environments. Silica sand for water filtration Silica sand is an effetive filtration bed in the removal of contaminants in both processing of wastewater and in the filtration of the drinking water. Silica sand neutralizes the acidic elements to maintain optimal pH balance in water filters. As it is chemically inert, it will not react when exposed to acids, contaminants, volatile organics or solvents. Metal Casting & Production Silica sand is an essential part of the production of steel, ferrous and nonferrous foundry industries for de-oxidation and grain refinement. For obtaining desired internal or external shapes, metal parts are cast in silica sand. It is a preferred choice for castings that involve cast iron, steel, titanium and also used to clean the casting surfaces. Paints & Coatings Silica sand constitutes of high-performance properties such as brightness, reflectance, oil absorption and colour-consistency. These properties help to improve the overall appearance and durability of industrial and architectural paints and coatings. Its low oil absorption nature improves finishing colour that makes a durable coating rich in pigments. Silica fillers improvement retention and also provide resistance to dirt, mildew, weathering and cracking

Silica sand,� also known as quartz sand, white sand, or industrial sand,� is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz â?? a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on� Mohs hardness scale, making it ideal for use as� filtration media� and� abrasive blasting sands. Although quartz is often white or colourless, it can come in a wide range of shades. The colour of each sand deposit depends largely on the variety of minerals and rock detritus that make up the resource. In order to be considered a silica sand the material must contain at least 95% SiO2 and less than 0.6% iron oxide. If the sand does not meet this criteria, it will qualify as whatâ??s often called â??regularâ?? sand. Regular sand,� also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. For example, typical brown sand used for� concrete applications� can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium, and other trace elements/minerals.
