The preparation of calcium phosphate ceramic powder mainly includes wet method and solid reaction method. Wet methods include: hydrothermal reaction method, aqueous solution precipitation method, sol-gel method, in addition, organic precursor thermal decomposition method, microemulsion medium synthesis method, etc. The research objective of various preparation processes is to prepare calcium phosphate powder with uniform composition and fine particle size.

Solid state reaction method (reaction without oxygen) often gives products with stoichiometry and complete crystallization, but they require relatively high temperature and heat treatment time, and the sinterability of this powder is poor.

Calcium phosphate ceramic materials obtained by hydrothermal method generally have high crystallinity and Ca / P close to stoichiometric value.

The advantages of the solution precipitation method are simple and reliable process, high purity of the composite, more suitable for experimental production than other methods, and nano-sized fiber particle powder can be prepared under the condition that the temperature does not exceed 100 ℃. Hydroxyapatite coating can also be prepared by solution precipitation method.

Sol gel method can be used to prepare amorphous, nano-sized calcium phosphate ceramic powder with Ca / P ratio close to stoichiometric value. The advantages of sol gel method are high purity, superfine, high uniformity, controllable particle shape and size, reaction at room temperature and simple equipment; The disadvantages are that the chemical process is complex, measures need to be taken to avoid agglomeration and environmental pollution caused by liquid solvents.

Solution precipitation method and sol gel method are the preferred preparation methods of calcium phosphate ceramic powder
