Latest Patents

Singh P Kumar holds a patent for a process for the preparation of polycrystalline silicon ingots. This invention involves a detailed method that includes providing a first layer of coating on the inside walls of a mold with a slurry of silicon nitride powder in an organic binder dissolved in a solvent. The process continues by charging the coated mold with silicon pieces along with calcium chloride or calcium fluoride. The mold is then heated to a temperature range of 1420°C to 1500°C to melt the silicon. After reaching the desired temperature, the mold is withdrawn slowly from the hot zone of the furnace, allowing the solidification of the melt to start from the bottom and proceed towards the top. Finally, the mold is cooled to room temperature under an inert atmosphere, and the polycrystalline silicon ingot is removed.
