| Abstract: | The dehydration temperature of phosphogyposum was measured by differential thermal analysis in this paper. The setting and hardening properties of phosphogypsum were researched in this paper. Academic gist is offered for the feasibility for the manufacture of gypsum in lower temperature, the paper is a advisable complementarity for the retarder's theory of retardance. |
