Frequently Asked Questions
What is the purity level of your nano-hydroxyapatite powder?
Our nano-hydroxyapatite powder has an assay of ≥96%, meeting both pharmacopoeia standards and relevant GB standards for heavy metal content including As, Cd, Hg, and Pb.
What particle sizes are available for the nano-hydroxyapatite powder?
We offer three average particle sizes: 20 nm, 40 nm, and 60 nm, allowing customers to select the most suitable grade for their specific application requirements.
Is nano-hydroxyapatite safe for use in toothpaste for children?
Yes. Nano-hydroxyapatite is non-toxic, non-irritating, and free from immune rejection due to its compositional similarity to human bone and tooth tissue. It is widely used as a fluoride-free alternative in children's toothpaste and oral care products.
Can nano-hydroxyapatite be used for heavy metal removal in water treatment?
Yes. Thanks to its high adsorption capacity, nano-hydroxyapatite is effective at removing heavy metal ions such as Pb, Cd, Cu, and Ni, as well as fluoride ions from both industrial wastewater and drinking water.
What packaging options are available, and how should the product be stored?
The product is available in 1kg/bag, 5kg/bag, and 25kg/drum packaging. It should be stored in a sealed, dry, and cool environment, protected from moisture and direct sunlight to maintain its quality and performance.
Is nano-hydroxyapatite suitable for use as a chromatography packing material?
Yes. Nano-hydroxyapatite can serve as a chromatography packing material for the separation and purification of proteins, enzymes, and nucleic acids. It is also used as a catalyst carrier, immobilized enzyme carrier, and chromatographic separation medium in chemical and biochemical industries.
