Summary: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 【課題】土壌および水中における固液分離能、運搬性、および透水性などの性能が向上したＤＣＰＤである花冠状第二リン酸カルシウム二水和物を提供する。【解決手段】花冠状第二リン酸カルシウム二水和物は、微小粒子が放射状に凝集した花冠様の形状を有する花冠状第二リン酸カルシウム二水和物であって、前記花冠状第二リン酸カルシウム二水和物は、その体積基準の粒度分布をヒストグラムに基づく折れ線グラフとして表わす場合、前記折れ線グラフは、横軸に粒径を対数により示す階級をとり、かつ縦軸に粒子数を示す度数をとることにより表され、前記折れ線グラフは、正規分布に近似した前記粒度分布を示し、かつ前記度数が最大となる前記階級よりも前記階級が小さい側にショルダー構造を有する。【選択図】図１
