Frequently Asked Questions
❓ What is nano-hydroxyapatite and how does it differ from regular hydroxyapatite?
Nano-hydroxyapatite (nHA) refers to hydroxyapatite particles at the nanometer scale (typically 20–100 nm). Compared to conventional hydroxyapatite, nHA has a significantly higher specific surface area, superior biocompatibility, and enhanced bioactivity, making it more effective for bone repair, drug delivery, and adsorption applications.
❓ What particle sizes are available for this nano-hydroxyapatite powder?
This product is available in three average particle sizes: 20 nm, 40 nm, and 60 nm. Different particle sizes are tailored for specific application scenarios and formulation requirements.
❓ Is nano-hydroxyapatite safe for use in toothpaste and oral care products?
Yes. Nano-hydroxyapatite is widely recognized as safe for oral care use. Its composition closely mirrors that of natural tooth enamel and bone mineral. It is non-toxic, non-irritating, and does not trigger immune rejection. It is commonly used as a fluoride-free alternative in toothpaste for children and individuals with tooth sensitivity.
❓ How should nano-hydroxyapatite powder be stored to maintain its quality?
The powder should be stored in a sealed container in a dry, cool place, away from moisture and direct sunlight. Proper storage conditions help prevent agglomeration and maintain the material's physicochemical properties over time.
❓ Can nano-hydroxyapatite be used for heavy metal removal in water treatment?
Yes. Thanks to its high specific surface area and strong adsorption capacity, nano-hydroxyapatite is highly effective at removing heavy metal ions such as Pb, Cd, Cu, and Ni, as well as fluoride ions from water. It is used in both industrial wastewater deep treatment and drinking water purification systems.
❓ What packaging options are available for standard orders?
Standard packaging options include 1 kg/bag, 5 kg/bag, and 25 kg/drum to suit different purchase volumes — from laboratory research to industrial-scale application.
