Purity of Si is 2N to 4N, with a particle size distribution of 50nm to 3mm. Customizable according to needs.
Our company offers 'Silicon (Si) powder' that can be customized for purity and particle size distribution according to application needs. Si purity options include 2N (Si > 99.0%), 3N (Si > 99.9%), and 4N (Si > 99.99%), with particle size distributions available as ultrafine powder (100nm and above), powder (1.0μm and above), and granules (1-3mm). We also provide 'ultrafine powder' that has been micronized to 50nm through plasma arc synthesis, which can achieve Si purity of 2N. 【Features】 ■ Manufacturing methods for ultrafine powder to granules: dry jet mill, dry ball mill ■ Shipping for ultrafine powder to granules ranges from a minimum of 1kg to a maximum of about 50 tons per month ■ Ultrafine powder shipping ranges from a minimum of 1kg to a maximum of about 500kg per month ■ A Certificate of Analysis (COA) is provided for each lot upon shipment *For more details, please refer to the documentation.
