摘要: Method for producing vaterite wherein a mixture of particles containing calcium in oxide and/or hydroxide form is treated reactive medium an acid salt organic amine order to transform the soluble and obtain whose pH, so called process has value higher than 10. CO2 introduced subjected stirring until pH reaches saturation close 0.83 x at flow rate lower 50g CO2/hour/litre as substantially spherical vaterite.
