Method of producing a metal carbonate bonded article and carbonate bonded article

Method of producing a carbonate bonded article, comprising preparing a particulate material comprising metal compounds of one or more transition/post-transition metals, in particular selected from the group consisting of iron and zinc, shaping the particulate material to obtain a shaped precursor, and reacting the shaped precursor with a source of carbonate or bicarbonate ions and with a source of water in a reaction environment at a temperature between 10°C and 150°C and a pressure of at least 1 bar, wherein the one or more sources of transition and/or post-transition metal ions react with the carbonate or bicarbonate ions and form at least 0.5% by weight of carbonates of the one or more metals thus transforming the shaped precursor into the carbonate bonded article. A content of the transition and/or post-transition metal compounds in the particulate material is at least 20% by weight of the particulate material when dry.
