I'm reaching out to request a quotation for 15 kg of Ge powder. I'm looking for a product with a minimum purity of 4N, ensuring high quality for my application. Additionally, the particle size should fall within the range of 40 to 100 microns, which is crucial for my processing needs. Could you please provide the pricing, availability, and any relevant specifications for this product? It would also be helpful to know about your lead times and shipping options. Looking forward to your prompt response. Thank you!
