Latest Patents

Anna Derdacka holds a patent for a revolutionary method for obtaining aluminum oxide. This method involves subjecting smelted metallurgical slag to slow cooling followed by self-decomposition through the concurrent application of ultrasound or high-frequency vibrations. This process accelerates the formation of a polymorphous, crystalline, high-temperature modification of calcium aluminate, identified as 12 CaO·7Al₂O₃, which can be efficiently lixiviated with aqueous soda solutions. The subsequent recovery of aluminum oxide from lye liquors illustrates her innovative approach, and the residue is processed to produce standard Portland clinker, maintaining a minimal clinker-to-aluminum oxide ratio.
