Nishimura No.		APA-90
Main Component		Ca3(PO4)2
Bulk Density	g/cm3	2.77
Bending Strenght	MPa	30

（Reference:Bulk density of pearl is 2.65）

Application

Pearl core material（Patent No.2958579）
Based on our testing, we have checked a performance of this material to become a core of pearl.

This material is expected to be used as a alternative bone.

Nano Powder

Pulverized sintered apatite by a bead mill and freeze-drying.

For apply to cosmetic/ toothpaste/Quasi drag, We took a safety test by JFRL(Japan Food Research Laboratories)
