FAQs About Silicon Powder & Silicon Metal Procurement
What's the difference between silicon metal grades like 441, 553, and 2202?
Answer: Silicon metal grades indicate impurity levels – the numbers represent maximum percentages of iron, aluminum, and calcium respectively. For example, 441 grade contains max 0.4% Fe, 0.4% Al, 0.1% Ca, while 553 has 0.5% Fe, 0.5% Al, 0.03% Ca. Grade 2202 offers higher purity with only 0.2% Fe, 0.2% Al, 0.02% Ca. Choose based on your application: 441/553 for aluminum alloys, 2202 for chemical applications requiring lower impurities.
Can you customize particle size distribution for high-purity silicon powder?
Answer: Yes, we offer complete customization from 0.1μm to 425μm particle sizes. Our standard ranges include 0.1-0.5μm, 0.5-2μm, 2-75μm, 58-125μm, and 75-425μm. We can also create specific distributions like 90% passing through designated mesh sizes. Our R&D team works with customers to optimize particle characteristics for applications like battery anodes, thermal paste, or semiconductor processing.
What's your minimum order quantity(MOQ) and typical lead times?
Answer: MOQ varies by product: typically 1-5 tons for high-purity silicon powder and 20-25 KG for silicon metal. Standard grades have shorter lead times (7-14 days), while customized specifications require 2-4 weeks. High-purity 5N grades may need 3-5 weeks due to additional purification processes. We maintain inventory of popular grades to expedite delivery for urgent requirements.
Which silicon materials work best for lithium battery anode applications?
Answer: For battery anodes, we recommend our 4N (99.99%) or 5N (99.999%) silicon powder with particle sizes between 50-500nm to 5μm. The ultra-low impurity levels (Fe, Al, Ca <2-30ppm) prevent unwanted reactions that reduce battery performance. Smaller particles offer better electrochemical performance but require careful handling. Our technical team can recommend optimal specifications based on your battery chemistry and processing requirements.
How do you ensure consistent quality across different batches?
A: Our ISO9001-certified facilities use advanced ICP-OES and ICP-MS analyzers in 1000-class clean laboratories. We implement 9-point sampling from each ingot and test 20-30% of every shipment. Each batch comes with detailed certificates of analysis showing chemical composition, particle size distribution, and physical properties. Our quality control system tracks every production step to ensure batch-to-batch consistency.
Do you provide technical support for international customers?
Absolutely. Our multilingual technical team offers comprehensive support including material selection guidance, application consulting, and troubleshooting. We provide detailed technical data sheets, safety documentation, and can arrange video consultations for complex applications. Our export department handles all shipping documentation, customs requirements, and logistics coordination to ensure smooth international delivery to over 50 countries worldwide.
