| titleOfInvention | A kind of acidolysis Wingdale prepares the method for high purity aragonitic nano-calcium carbonate |
| abstract | The invention discloses the method that a kind of acidolysis Wingdale belonging to technical field of nanometer material preparation prepares high purity aragonitic nano-calcium carbonate.The method for raw material with the abundant ore resource Wingdale of occurring in nature, does not add any additive, direct acidleach, utilizes the CaCl after acidleachn 2 -NHn 4 cl filtrate and sodium carbonate solution generation replacement(metathesis)reaction, prepare high purity aragonitic nano-calcium carbonate.Present method avoids high-temperature calcination, can energy efficient, the dust pollution produced when reducing coal combustion, solves the problem that ore resource utilization ratio is low, can accomplish that clean environment firendly is produced.The present invention is simple to operate, and cost is low, and obtained aragonite calcium carbonate productive rate is high, purity is high, is easy to realize suitability for industrialized production. |
