Latest Patents

Khalil Zeaiter holds a patent for a method of producing high purity silicon. The patent describes a process that involves providing molten silicon containing 1-10% by weight of calcium, casting the molten silicon, and crushing it. The crushed silicon undergoes a first leaching step in an aqueous solution of HCl and/or HCl+FeCl3, followed by a second leaching step in an aqueous solution of HF and HNO3. The leached silicon particles are then subjected to heat treatment at temperatures between 1250°C and 1420°C for at least 20 minutes. Finally, the heat-treated silicon undergoes a third leaching step in an aqueous solution of HF and HNO3. This innovative method is aimed at enhancing the purity of silicon, which is crucial for various applications.
