摘要： A surface-reacted calcium carbonate is described. In embodiments, the surface-reacted calcium carbonate is obtained by a process comprising treating a calcium carbonate-comprising material with at least one H3O+ ion donor, carbon dioxide, and at least one water-soluble metal cation source in an aqueous medium to form an aqueous suspension of surface-reacted calcium carbonate.
