Grade Metallic Si Pure Silicon

ZhenAn's chemical-grade silicon (99.9%-99.99% purity) meets exacting standards for polysilicon production and specialty chemical synthesis. Our zone-refined 6N+ material (99.9999% Si) serves semiconductor manufacturers, with controlled boron/phosphorus content below 0.1ppb. Beyond standard lumps, we provide atomized silicon powder (D50: 5-150μm), etched silicon wafers (200mm/300mm), and nano-silicon particles (50-200nm) for advanced applications. The plasma-assisted milling process achieves spherical morphology with <3% ovality deviation.

Quality Infrastructure: Our ISO/IEC 17025 accredited lab conducts 47-point quality checks using GD-MS and ICP-OES analysis. The material certification package includes 3D microstructure mapping and batch-specific thermogravimetric analysis reports. Annual BSI audits confirm consistent compliance with IATF 16949 automotive standards.

At ZhenAn International, we view every order as a step toward building a lasting partnership. Trust in our legacy of excellence, rely on our technical prowess, and experience the difference of working with a supplier that understands your industry's unique challenges.
