韩国采购需求：硼酸、氟化镁、高纯锑、氧化硒、硅基体、硅柱

I am reaching out to inquire about the pricing for specific materials critical to the semiconductor industry. We are particularly interested in Boron, Arsenic, and Antimony, specifically in the 5N and 6N grades. A detailed quotation would be greatly appreciated, including any bulk pricing options you may offer. Additionally, it would be helpful to know the availability and lead times for these materials, as well as any relevant specifications or quality certifications that come with them. Your prompt response will be valuable for our procurement planning. Thank you!
