印度采购需求：铋锭、铋丸、铋粉、碲化铋、三氧化铋、电解钴

I'm looking to procure 5 kilograms of germanium ingots for a project we're currently developing. Could you please provide details on the available grades and specifications? Also, I'd appreciate it if you could include pricing, lead time, and any minimum order requirements. Additionally, if you have information about the production process or quality assurance measures you follow, that would be great. We're particularly focused on ensuring high purity and consistency in the materials we source. Let me know if you need any more details from my side!
