Embodiment 1
[0020] 1) Fully crush 100 grams of dolomite, add 5 liters of 0.5M HCl solution, continue to stir and react for 0.5 hours, filter out the bottom insoluble residue, and obtain dolomite acidification solution;
[0021] 2) Add 1 liter of 0.5 mol / L sulfuric acid solution to the dolomite acidification solution, heat it under microwave radiation for 1 minute, then transfer it to a 90-degree water bath to age for 2 hours, filter, wash, and dry the solid phase at 50 degrees Dry to obtain calcium sulfate dihydrate whiskers.
Embodiment 2
[0023] 1) Fully crush 100 grams of dolomite, add 0.5 liter of 5M HCl solution, continue to stir and react for 5 hours, filter out the bottom insoluble residue, and obtain dolomite acidification solution;
[0024] 2) Add 10 liters of SO to the dolomite acidification solution 4 2- Na with an ion concentration of 0.05mol / L 2 SO 4 and K 2 SO 4 The mixed solution was heated under microwave radiation for 3 minutes, then moved into a 90-degree water bath to age for 8 hours, filtered, washed, and the solid phase was dried at 200 degrees to obtain anhydrous calcium sulfate whiskers.
Embodiment 3
[0026] 1) Fully crush 100 grams of dolomite, add 2 liters of 1M HCl solution, continue to stir and react for 2 hours, filter out the bottom insoluble residue, and obtain dolomite acidification solution;
[0027] 2) Add 5 liters of 0.1mol / L MgSO to the dolomite acidification solution 4 The solution was heated under microwave radiation for 2 minutes, then moved into a 70-degree water bath to age for 5 hours, filtered, washed, and the solid phase was dried at 120 degrees to obtain calcium sulfate hemihydrate whiskers.
