Phosphate → Tricalcium Phosphate

Two stock solutions were prepared as follows: solution A by mixing 600 ml of calcium stock solution (1000 ppm of Ca++ as CaCO3) and 600 ml of distilled water, and solution B by mixing 24 ml of phosphate stock solution (800 ppm as orthophosphate) and 1176 ml of distilled water. Both stock solutions were then adjusted to pH 9 with 1 percent sodium hydroxide. To each of a series of bottles was then added a 50 ml portion of solution A. To all but one of the bottles (the control) was then added 0.2 ml of 0.5 percent active solution of a polymer (the control bottle had no polymer). To each of the bottles was then added 50 ml of solution B while stirring. The bottles were then placed in an oven held at 70° C.
