High Purity Quartz Crucible

Semicorex High Purity Quartz Crucible is a specialized consumable device made from high-purity quartz sand, widely applied in the photovoltaic and semiconductor industries. It is designed to support continuous crystal pulling under high-temperature conditions and is primarily used for holding polycrystalline silicon materials during the crystal growth process. This product is critical for ensuring the quality and efficiency of single-crystal silicon production.

High Purity: The quartz crucible is manufactured using ultra-high-purity quartz sand to minimize contamination during the crystal pulling process. Its exceptional purity ensures a clean environment, which is essential for producing high-quality silicon ingots.
Thermal Resistance: The quartz crucible exhibits outstanding thermal properties. Its deformation temperature is approximately 1100°C, while its softening point reaches around 1730°C. It can withstand continuous usage at temperatures up to 1100°C and short-term exposure to temperatures as high as 1450°C. These characteristics enable the crucible to perform reliably under the demanding conditions of silicon crystal growth.
Homogeneity and Structural Integrity: The crucible’s homogeneous composition and robust structural integrity contribute to its durability and reliability. These qualities are vital for maintaining consistent performance during high-temperature operations.
Dimensional Stability: The crucible retains its shape and size even under prolonged exposure to extreme temperatures, ensuring optimal compatibility with crystal pulling systems.
Chemical Resistance: The material’s inherent resistance to chemical reactions under high-temperature conditions prevents interactions with molten silicon or other substances, preserving the purity of the silicon crystal.

 

The High Purity Quartz Crucible is a key auxiliary material in the Czochralski (CZ) crystal pulling process, a widely used method for producing high-purity silicon ingots. It plays a pivotal role in supporting the growth of single-crystal silicon by holding molten silicon during the pulling process, ensuring the integrity and quality of the resulting silicon ingot. In the semiconductor industry, it facilitates the production of ultra-pure silicon wafers, which are essential for creating integrated circuits and other electronic components. Additionally, the crucible is indispensable in the photovoltaic sector for manufacturing monocrystalline silicon wafers used in high-efficiency solar cells.

Enhanced Crystal Quality: The high purity and thermal stability of the quartz crucible significantly reduce the risk of contamination and structural defects, ensuring superior crystal quality.
Optimized Process Efficiency: The crucible’s reliability and durability minimize interruptions during the crystal pulling process, leading to improved operational efficiency.
Cost-Effectiveness:Although it is a consumable device, the quartz crucible’s extended lifespan and consistent performance provide long-term value by reducing the frequency of replacements.
Customization Options: High Purity Quartz Crucibles are available in various sizes and configurations to meet the specific requirements of different crystal growth systems.
