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)
