Frequently Asked Questions (FAQ)
Q What is nano hydroxyapatite and how does it differ from regular hydroxyapatite?
Nano hydroxyapatite features an average particle size of 20–60 nm, which is significantly smaller than conventional hydroxyapatite. This nanoscale size gives it a much higher specific surface area, enhanced biocompatibility, and superior adsorption and bioactivity performance compared to standard-grade material.
Q Is nano hydroxyapatite safe for use in toothpaste for children?
Yes. Nano hydroxyapatite is non-toxic, non-irritating, and free from immune rejection responses. It is widely used as a fluoride-free alternative in toothpaste and oral care products, making it suitable for children and individuals with sensitive teeth.
Q What particle sizes are available for this nano hydroxyapatite powder?
This nano hydroxyapatite powder is available in three average particle sizes: 20 nm, 40 nm, and 60 nm. Different particle sizes may be selected depending on the specific application requirements, such as oral care, biomedical use, or water treatment.
Q Can nano hydroxyapatite be used for heavy metal removal in water treatment?
Yes. Nano hydroxyapatite possesses strong adsorption capabilities for heavy metal ions including Pb, Cd, Cu, and Ni, as well as fluoride ions. It is effectively used for deep treatment of industrial wastewater and purification of drinking water.
Q What packaging options are available and what are the storage requirements?
Nano hydroxyapatite is available in 1 kg/bag, 5 kg/bag, and 25 kg/drum packaging. It should be stored in a sealed, dry, and cool environment with protection against moisture and direct sunlight to maintain its quality and performance.
Q What quality standards does this nano hydroxyapatite comply with?
This product meets multiple quality benchmarks including GBB 1871.1 for Ca:P ratio, GB10724 for Cd and Pb content, GB9723 for Hg content, and Pharmacopoeia standards for arsenic (As) and total heavy metal elements. The assay purity is ≥96%.
