Procedure

39.3 Grams of sodium phosphate were dissolved in 150 grams of water (Solution A). In a separate beaker, 22.65 grams of calcium chloride were dissolved in 150 grams of water (Solution B). Each of the above solutions were added simultaneously to 200 grams of water, while being sheared at speeds of 12,000 rpm. This shearing was necessary since the viscosity resulting from the in situ formation of tricalcium phosphate (TCP) particulates needs to be broken down into submicron size in order to be effective as a stabilizer. The amount of in situ TCP generated in this case was 16.0 grams.
