Title: Jerzy Grzymek: Innovator in Aluminum and Cement Production
Introduction
Jerzy Grzymek is a notable inventor based in Warsaw, Poland. He has made significant contributions to the fields of aluminum and cement production, holding a total of 2 patents. His innovative methods have the potential to enhance the efficiency and sustainability of these materials.
Latest Patents
Grzymek's latest patents include a "Process for producing high-purity alumina" and a "Method for obtaining aluminum oxide." The first patent describes a process where a low-grade aluminum and silicon-containing starting material is intimately mixed with limestone. This mixture is then fluidized and preheated to a temperature between 700°C and 900°C, followed by a sintering phase lasting 5 to 10 minutes. This method allows for the recovery of aluminum through the extraction of the sintered powder produced. The second patent outlines a method for obtaining aluminum oxide from smelted metallurgical slag. This slag undergoes slow cooling and self-decomposition, aided by ultrasound or high-frequency vibration, which accelerates the formation of a high-temperature modification of calcium aluminate. The aluminum oxide is then recovered from lye liquors after extraction, while the residue is burnt to standard Portland clinker.
