Latest Patents

Richard B Grekila holds a patent for a method titled "Encapsulation of solids in alpha-alumina." This patent describes a process for encapsulating soluble or colloid solids in alpha-alumina. The method involves forming a solution or colloid of the solids in a liquid with low surface tension, allowing it to wet a non-particulate transition alumina with at least 40% porosity. The solution is then allowed to impregnate the alumina's pores, followed by evaporation of the liquid. The alumina is subsequently heated to its alpha-Al2O3 transformation temperature, effectively entrapping waste within its matrix and sealing the pores. After cooling, the surface of the alumina can be washed to remove any untrapped solids.
