Title Ceramic particle group and method for production thereof and use thereof
Abstract The object of the invention is to provide a ceramic particle group dispersed in a solvent in a state of primary particles of single crystal, a method for production thereof, and use thereof.
The ceramic particle group is characterized in that the ceramic particle group is dispersed as primary particles of single crystal, or a cluster of primary particles of single crystal that are held together by ionic interactions.
A 70% or greater proportion of the ceramic particles exist as primary particles of single crystal under optimum conditions.
The ceramic particles have a particle diameter in a range of 10 nm to 700 nm, and a coefficient of variation of particle diameter of the ceramic particles is no greater than 20%.
The ceramic particles are hydroxyapatite sintered particles and can be used for multiple purposes, such as a filler for chromatography, dentistry material, and so on.
