Latest Patents

Lafon's most recent patent is titled "Method for producing an alumina gel having a high dispersibility and a specific crystallite size." This patent describes a process for preparing alumina gel in a single precipitation step. The method involves dissolving an aluminum precursor, aluminum chloride, in water at a temperature ranging from 10°C to 90°C. The pH of the solution is maintained between 0.5 and 5 for a period of 2 to 60 minutes. Following this, the pH is adjusted to between 7.5 and 9.5 by adding sodium hydroxide, resulting in a suspension at a temperature of 5°C to 35°C for 5 minutes to 5 hours. The process concludes with a filtration step, notably without any washing steps. The resulting alumina gel boasts a high dispersibility index, specifically over 80%, with a crystallite dimension of 0.5 to 10 nm, and controlled chlorine and sodium content.
