Long-term stable (>2 years) hydrocolloids of hydroxyapatite (HA) were synthesized via a low-temperature (18-50 °C) reaction of aqueous ammonium phosphate with calcium nitrate in the presence of citrate ions, followed by an aging process at high temperature (80-99 °C) for 4 h. Changing the reaction and/or aging temperature seldom yielded stable HA hydrocolloids. The as-prepared hydrocolloids were desalinated through ultrafiltration where their average particle size gradually decreased, bottomed… CONTINUE READING
