P. Pacak et M. Skokanek, THERMAL STUDY OF THE SOLID-STATE REACTION OF AMMONIUM-SULFATE WITH CALCIUM-PHOSPHATE, Journal of thermal analysis, 39(5), 1993, pp. 551-557
The reaction of ammonium sulfate with calcium phosphate was investigat
ed by means of thermoanalytical and chemical methods, at 300-degrees-4
00-degrees-C, at mole ratios of the starting compounds of 1:1, 1:2 and
1:3. The reaction can be useful for the treatment of waste ammonium s
ulfate to obtain phosphate fertilizer.
