| Abstract: | The experimental method and the optimal process conditions for the production of crystal calcium polysulfide is studied.It includes raw material mass ratio CaO∶S∶H 2O=1∶1.9∶6,small boiling for 45 min at atmospheric pressure,the density of the solution should amount to 1.38 g/ml by dehydrate in low temperature,crystallizing in -10 ℃.The product that CaS 4 content over 47% is obtained. |
