摘要：
High-purity calcium carbonate of vaterite type was directly obtained from calcium sulfate and ammonium carbonate in ammonium sulfate matrix. This matrix can successfully break the limitations of reactant concentration, temperature, and stirring speed on vaterite. An orthogonal experiment combined with back propagation neural network was then performed to optimize the impurity in vaterite. Under the optimum conditions, 99.9% vaterite was obtained.
