The invention relates to the chemistry of zirconium. It relates to reactive derivatives of zirconium, characterized in that they are in the form of a pulverulent white solid which is not crystallized and dry in appearance, and consist of metazirconic acid ZrO(OH)2 accompanied by free or weakly bound water, it being possible for some of the OH- ions to be replaced by halide ions, the ZrO2 content of these derivatives being from 60 to 92% by weight inclusive and the water content of these derivatives ranging from 3 to 40% and the halide ion content of these derivatives being capable of ranging up to approximately 5% by weight, and to a process for their preparation. The solid derivatives of the invention can be easily converted into usual reactive derivatives of zirconium by reaction with an aqueous solution of an acid.
