Abstract

The invention provides a preparation device and method of a bundle-shaped strontium carbonate crystal. In a reaction device, strontium chloride hexahydrate and ammonium bicarbonate are used as reactants and gelatin is used as a bionic induction agent to prepare the bundle-shaped strontium carbonate crystal. After reaction is finished, a product is filtered and washed and is dried at 105 DEG C for1h to obtain the bundle-shaped strontium carbonate crystal composed of a crystal bar. The reaction device is composed of a No. 1 material groove, a sedimentation groove and a No. 2 material groove. The diameter of the crystal bar in bundle-shaped strontium carbonate is 30 to 50nm and the length of the crystal bar is 200 to 700nm; the product has the purity greater than or equal to 99 percent of the yield of 96 to 98 percent. The product provided by the invention has the advantages of high purity, high yield, small diameter, large crystal length-diameter ratio, low raw material price, simple and feasible method, low energy consumption, convenience for industrial production and the like.
