Application

Calcium phosphate nanopowder serves a multifaceted role in various applications, leveraging its composition of calcium phosphates similar to tribasic calcium phosphate, which is a white, odorless, tasteless powder and a key mineral in bones and teeth. This nanopowder is primarily used to enhance bone health, thanks to its osteogenic properties, and is widely utilized in the prevention and treatment of osteoporosis. It acts as a therapeutic aid in tissue replacement, aiding in the repair of bone defects, and serves as a versatile drug carrier, efficiently delivering medications to the bone. In manufacturing, calcium phosphate nanopowder contributes as a crucial component in the production of phosphoric acid and fertilizers. In pharmaceuticals, it functions as a filler and binder in tablet and capsule formulations, facilitating direct-compression or wet-granulation processes. The powder's beneficial properties are further amplified when incorporated into biodegradable polymer composites or applied to biocompatible surfaces, promoting the adhesion and proliferation of osteoblast cells. Furthermore, in the realm of food applications, it acts as an effective anticaking agent, ensuring the smooth production and storage of products.
