Title:
花冠状第二リン酸カルシウム二水和物の製造方法
Document Type and Number:
Japanese Patent JP7002725
Kind Code:
B2
Abstract:
To provide coronary secondary calcium phosphate dihydrate that is DCPD of which performances such as the solid-liquid separability, transportability, and permeability in soil and in water were improved.SOLUTION: Coronary secondary calcium phosphate dihydrate is coronary secondary calcium phosphate dihydrate having a coronary shape in which fine particles are radially flocculated, when in the coronary secondary calcium phosphate dihydrate, the particle size distribution based on a volume is represented as a polygonal line graph based on a histogram, the polygonal line graph is represented by taking a grade showing a particle size by a logarithm on a horizontal axis, and by taking a degree of number showing the number of particles on a vertical axis, the polygonal line graph shows the particle size distribution similar to a normal distribution, and has a shoulder structure provided on a side where the grade is smaller than the grade where the number of grade becomes a maximum.SELECTED DRAWING: Figure 1
