FAQ
Q: Can samples be provided for testing?
A: Free samples (up to 500g, limited to 3 specifications) are available upon providing application details.
Q: Does surface modification affect purity?
A: The modification layer only coats particle surfaces; FTIR testing confirms purity remains ≥99%.
Q: What is the minimum order quantity (MOQ)?
A: 1 MT for standard specifications; 500kg for customized specifications.
