Abstract
A method of producing powder by using a first liquid and a second liquid to be mixed with the first liquid, the first liquid containing a first raw material and the second liquid containing a second raw material. The method comprises: mixing the first liquid and the second liquid to obtain a mixture; stirring the mixture for reacting the first raw material and the second raw material to thereby obtain a synthetic material and a slurry containing aggregates of the synthetic material; and drying the slurry to obtain powder of the synthetic material. In the mixing the first liquid and the second liquid, particle strength of the powder is adjusted by setting an initial temperature of mixing the first liquid with the second liquid.

A method of producing powder by using a first liquid and a second liquid to be mixed with the first liquid, the first liquid containing a first raw material and the second liquid containing a second raw material, and the method comprising:
- mixing the first liquid and the second liquid to obtain a mixture;
- stirring the mixture for reacting the first raw material and the second raw material to thereby obtain a synthetic material and a slurry containing aggregates of the synthetic material;
- and
- drying the slurry to obtain powder of the synthetic material,
- wherein in the mixing the first liquid and the second liquid particle strength of the powder is adjusted by setting an initial temperature of mixing the first liquid with the second liquid.
Powder constituted of hydroxyapatite as a main component thereof, the powder obtained by drying a slurry containing aggregates of the hydroxyapatite and granulating the aggregates,
- wherein the powder is sintered to obtain sintered powder including sintered particles, and then the sintered particles are classified so that an average particle size thereof falls within 4±5 μm, wherein when a compression particle strength of the classified sintered powder is measured, the compression particle strength is 1.0 MPa or more.
