Procedure

To 50 l of an 0.07 M solution of bisodium phosphate, continually stirred by means of a vibrator, 50 l of an 0.07 M solution of calcium chloride are added in 28 seconds; the pH of the mixture is adjusted to 7.1 with a solution of normal sodium hydroxide, following the addition of the CaCl2. The 100 l of calcium phosphate gel thus obtained are left to stand until decantation of 85 l of liquid. The clear supernatant liquid is separated by siphoning and replaced by 85 l of aqueous solution of NaCl, 4 g/l.
