What Is Silicone? How Is It Made? - Wafer Process Systems
2020-1-23 Instead, people produce silicon via one of two ways – either from sand (silicon dioxide) or from vein or lode deposits within the earth. When producing pure silicon from sand, manufacturers heat it at 2200 degrees Celsius. At that temperature, the pure crystalline silicon separates, and it becomes a compound that people can turn into wafers.
