Quartz Sand
Semicorex’s high-purity quartz sand is a superior material that plays a crucial role in advancing the semiconductor and photovoltaic industries.
High-purity quartz sand, also known as silica sand, silica powder, or silica dioxide powder. With a purity level of ≥99.995% SiO2, our quartz sand sets the standard for excellence and is essential for applications in the semiconductor and photovoltaic (PV) sectors.
Key Properties and Advantages of Ultra Pure Silica Powder
Minimal Thermal Expansion and Superior Thermal Shock Resistance: One of the primary benefits of our high-purity quartz sand is its low thermal expansion coefficient. This property is vital for components that undergo rapid temperature fluctuations, as it helps prevent cracking or deformation. Additionally, the silica powder’s high resistance to thermal shock ensures durability and longevity, even in challenging environments.
Excellent Dielectric Properties: The dielectric characteristics of our quartz sand make it highly suitable for use in the semiconductor industry, where electrical insulation and stability are paramount. These properties of silica powder ensure that electronic components remain reliable and efficient, even under high-stress conditions.
High UV Light Transmittance: Our high-purity quartz sand exhibits superior UV light transmittance. This feature is particularly beneficial for applications such as optical fibers and photovoltaic cells, where light absorption and transmission are crucial for optimal performance.
Applications of High-purity Quartz in the Semiconductor Industry
In the semiconductor industry, high-purity quartz sand is indispensable for the production of silicon metal, which forms the foundation for creating semiconductor wafers via the Czochralski process. This process involves melting polysilicon in a quartz crucible, from which a single crystal is drawn and sliced into wafers. The exceptional purity and thermal properties of our silica powder allow these components to withstand the extreme temperatures involved in wafer processing, ensuring the production of high-quality semiconductor elements.
Additionally, our quartz sand is essential for manufacturing high-purity quartz products, including tubes, rods, bars, plates, and crucibles. These components made from silica powder are critical in semiconductor device fabrication.

Impact of High Purity Silica Powder on the Photovoltaic Sector
In the photovoltaic industry, high-purity quartz sand plays a vital role in producing crystalline silicon (c-Si) cells and modules. silica powder’s unique anti-crystallization ability and excellent high-temperature resistance contribute to the creation of quartz products with fewer defects, such as bubbles, gas lines, and color lines. This ensures that photovoltaic cells and modules perform efficiently and have a longer operational lifespan.
By incorporating our high-purity quartz sand, manufacturers can produce PV cells that convert sunlight into electricity more effectively. This is particularly important as the global shift towards renewable energy sources accelerates, and the demand for high-performance photovoltaic cells continues to rise.
