Preparation of hydroxyapatite nanopowders via Sonochemistry-assisted microwave process

摘要

Sonochemistry-assisted microwave process provided an ultrafast, simple and green method to synthesize well-crystallized HAp nanopowders with Ca/P molar ratio close to theoretical value and high yield of 98.8% in ultra-short-period of 5 min. The ultrasound assistant apparently promoted the crystallization process and increased the specific surface area and dispersibility of the as-obtained products.
