The invention relates to a method for the treatment of cellulosic material. The method is comprising the steps of impregnation of the cellulosic material and treatment of the impregnated cellulosic material by a fumigation step or an evaporation step. Impregnation is performed with a metal ion (M) and at least one ion precursor (Z) yielding an impregnated cellulosic material. The at least one ion precursor (Z) provides an anion (A) or an anion (A) and a cation (Y) comprised within at least one metal salt solution (I) or with a metal salt solution (II) comprising a metal ion (M). The fumigation or evaporation step is yielding a cellulosic composite material comprising a compound: M(NH4)A， MYA or M(OH)x， wherein M is a metal.
