BIOACTIVE CRYSTALLIZED GLASS BEAD

摘要

PROBLEM TO BE SOLVED: To provide bioactive crystallized glass beads suitable as a filler for cement having biological activities, high mechanical strengths and little deterioration in mechanical strengths. SOLUTION: This bioactive crystallized glass bead contains Ca and the ratio of the intensity (I2) of diffraction peak at d=2.94 Åspacing of wallastonite and/or diopside over the intensity (I1) of diffraction peak at d= 2.94 Å of apatite satisfies the equation: 0
