Parameters of Excellent Quality And Good Metal Silicon Powder For Polysilicon
Metal silicon powder, also known as ferrosilicon or silicide, is an important compound used in various industries, particularly in the production of polysilicon, which is a crucial raw material for the semiconductor industry. The quality and parameters of metal silicon powder for polysilicon applications are critical for ensuring high-performance semiconductor devices. Here are some key parameters to consider:
1. Purity: High purity (99.999% or better) is essential for minimizing impurities that can cause defects in the final polysilicon product. Impurities like iron, carbon, and oxygen should be kept to a minimum.
2. Particle Size Distribution: A narrow particle size distribution ensures consistent reactivity and uniformity during the polysilicon synthesis process. A typical range for polysilicon powders is 40-150 microns, with a narrow spread.
3. Crystal Structure: Ferrosilicon particles should have a well-defined crystal structure, usually α-FeSi2 or β-FeSi2, which affects its reactivity and melting point.
4. Melting point: The melting point should be within a suitable range for the polysilicon production process, typically around 1420-1480°C.
5. Reactivity: Metal silicon powder must exhibit good reactivity with chlorine or hydrogen to form trichlorosilane or dichlorosilane, respectively, which are then used in the polysilicon synthesis loop.
6. Hygroscopicity: Low hygroscopicity is important to prevent moisture absorption, which can lead to chemical reactions and impurities in the polysilicon.
7. Nto Finish: Smooth and clean surface finish helps minimize impurities and surface defects that can impact the purity of the final polysilicon product.
8. Diamagnetic Properties: Ferrosilicon should have strong diamagnetic properties, which help maintain the purity of the reactor during the polysilicon production process.
9. Thermal Stability: The powder should have good thermal stability under high temperatures to ensure consistent performance throughout the polysilicon process.
10. Safety: The metal silicon powder should meet safety standards for handling and storage, including low toxicity and proper packaging to prevent accidental contamination.
Manufacturers and suppliers should provide documentation and certifications (piv txwv li, ISO 9001, IEC 61000-4-2) to ensure the quality and consistency of their products. It’s essential to work with a reliable supplier who can provide these parameters and meet your specific requirements for polysilicon production.
