Document Type and Number:
Japanese Patent JPH0517111
Kind Code:
A
Abstract:

PURPOSE: To produce hydroxyapatite ultra-fine particles having an uniform particle diameter by a simple production means at a low cost in a readily, industrially and massively producible state.

CONSTITUTION: A Ca(NO3)2/ammonia aqueous solution and a (NH4)2 HPO4/ammonia aqueous solution are dissolved in surfactant-water-nonpolar organic liquid system or surfactant-water-alkanol-nonpolar organic liquid system W/O microemulsion phases, respectively, and the solutions produced are mixed with each other to produce hydroxyapatite ultra-fine particles.
