Method for preparing vaterite phase containing calcium carbonate by adopting sodium sulfonate as crystal form control agent

The invention provides a method for preparing vaterite phase containing calcium carbonate by adopting sodium sulfonate as a crystal form control agent. The method includes the following steps: 1, weighing raw materials and an additive; 2, performing mechanical milling to raw materials and the additive; 3, removing raw materials calcium chloride and sodium carbonate not fully reacted and a by-product sodium chloride, and drying a product; 4, performing phase analysis to the product to obtain the product vaterite phase containing calcium carbonate powder. According to the method, the content ofthe vaterite phase containing calcium carbonate inside the product can be changed through adjusting experimental parameters, during the ball milling experiment, along with the increase of the additionamount of sodium dodecyl sulfate from 0.5 wt% to 70wt%, the content of vaterite is increased from 1.2% to 58.2%; in the method, as the mechanical milling is adopted, requirements on equipment and cost are low, no harmful toxi
