| titleOfInvention | PROCESS FOR THE PRODUCTION OF ALPHAHYDRATE PLASTER |
| abstract | Gypsum waste from chemical industry, esp. the filter cake from the phosphoric acid prodn., is introduced without washing and still wet into a soln. contg. as dehydration agent 50-10% NH4NO3 and 5-40% HNO3 (the total nitrate content calculated as HNO3 is 30-50%) at 70-100 degrees C under atmospheric pressure. NH4NO3 promotes the growth of CaSO4.0.5H2O crystals so that suspensions contg. 30-40% of solids can be used and, consequently, the dimensions of the appts can be reduced. A very pure prod. is obtd. |
