Synthesis method of hollow calcium hydroxide microspheres

The invention provides a method for synthesizing hollow calcium hydroxide microspheres, which comprises the following steps of: firstly, weighing corresponding anhydrous calcium chloride, anhydrous sodium carbonate and folic acid, mixing the weighed substances, uniformly mixing in a beaker by using water, putting into a polytetrafluoroethylene reaction kettle, putting into a drying oven, heating and reacting for 12 hours at 200 DEG C under the air condition, and cooling to room temperature to obtain the hollow calcium hydroxide microspheres. And cooling to room temperature, taking out, filtering, washing, drying, putting into a corundum crucible, roasting for 2 hours in an air atmosphere at 800 DEG C, naturally cooling to room temperature, taking out, and uniformly grinding to obtain white powder. According to the hollow calcium hydroxide microspheres prepared by the method, the synthesized product overcomes the defect that a traditional calcium hydroxide product is single in structure, the calcium hydroxide
