摘要： The invention relates to the field of technical ceramics and specifically relates to a method of synthesis for aluminum oxides of different crystalline structure and to the products obtained by said method. The aim of the invention is to provide a method of producing redispersible nanoparticulate corundum and nanoporous Al2O3 sintered products, said method using precursors and being viable on a commercial scale. To this aim, inter alia, a method of producing redispersible nanoparticulate corundum of an average particle size of D50
