Problems solved by technology

[0005] Although the current literature has reported methods for preparing calcium magnesium phosphate, most of them use calcium salts, magnesium salts, and inorganic phosphorus sources to directly mix and sinter to obtain calcium magnesium phosphate ceramics or cement materials, and few people directly synthesize them. Calcium Magnesium Phosphate Nano Powder
In addition, when inorganic phosphate is used as the phosphorus source, in the initial stage of the reaction, the calcium ions, magnesium ions and phosphate ions in the solution are all in a supersaturated state, and the crystals are easy to grow, and the size and shape are difficult to control.

Abstract

The invention relates to a calcium magnesium phosphate nanometer structure material and a preparation method thereof. The method includes the following steps of using water soluble calcium salt as a calcium source, water soluble magnesium salt as a magnesium source and phosphorus biological molecules as a phosphorus source; performing hydrothermal reaction on mixed water solution containing the calcium source, the magnesium source and the phosphorus source to obtain the calcium magnesium phosphate nanometer structure material. The phase and the morphology of the calcium magnesium phosphate nanometer structure material are regulated and controlled by means of regulating the molar ratio of the calcium source to the magnesium source.

Description

Technical field [0001] The invention relates to a calcium-magnesium phosphate nanostructure material and a preparation method thereof, in particular to a reaction system that uses water-soluble calcium salt as a calcium source, water-soluble magnesium salt as a magnesium source, and phosphorus-containing biomolecules as a phosphorus source. The preparation method for obtaining the calcium magnesium phosphate nanostructure material belongs to the field of biological material preparation. Background technique [0002] Calcium and magnesium are one of the main elements of the human body. They are essential nutrients for cell growth and play an important role in regulating various life activities of the human body. For example, magnesium can regulate the metabolism of bone tissue and affect the mineralization of minerals in bone tissue. And crystallization process. Calcium mainly exists in the hard tissues of human body such as bones and teeth in the form of amorphous calcium phosph...
