The present invention pertains to cheaper process for the preparation of quasi-crystalline boehmite containing additive in a homogeneously dispersed state. In this cheaper process an inexpensive quasi-crystalline boehmite precursor is and additive are combined and aged to form a quasi-crystalline boehmite containing additive in a homogeneously dispersed state. Suitable inexpensive quasi-crystalline boehmite precursors are aluminum trihydrate and thermally treated forms thereof and inorganic aluminum salts. Suitable additives are compounds containing elements selected from the group of rare earth metals alkaline earth metals, transition metals, actinides, silicon, gallium, boron, and phosphorus.
