Title:
POROUS MATERIAL OF HYDROXYAPATITE AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH06128051
Kind Code:
A
Abstract:
PURPOSE: To produce an inexpensive porous material of hydroxyapatite suitable for water treating material, adsorbent, ion exchanger, various carriers, etc.
CONSTITUTION: Hydroxyapatite crystal is precipitated on pore parts of a hardened material of hydraulic cement to give a porous material of hydroxyapatite. For example, Portland cement is mixed with 20% aqueous solution of sodium phosphate in a ratio of (liquid/solid) of 40% by weight, kneaded, then the kneaded material is still stood and cured in a room for 7 days and hardened to give a porous material of hydroxyapatite.
