摘要

Control of pH and temperature allows conversion of brushite to monetite of specific crystal habit: e.g., rectangular (needle) having a basal plane acute angle of approximately 90 DEG ; thin rectangular (plate) having a basel plane acute angle of approximately 84 DEG ; rhombohedral (plate) having a basal plane acute angle between 84 DEG and 63 DEG ; and rhombohedral (diamond) having a basal plane acute angle of approximately 63 DEG . In addition to habit, particle size distribution (PSD) and most frequent size (size) can be varied in a controlled manner.
