Metallic Silicon Powder For Making Silicon Wafers

It's important to note that metallic silicon powder serves as the initial material for the production of silicon wafers, but it undergoes extensive purification and crystal growth processes before it becomes suitable for semiconductor device fabrication. The silicon wafers used in the semiconductor industry have a much higher level of purity, typically exceeding 99.9999%.

Metallic silicon powder, also known as metallurgical-grade silicon (MG-Si), is a key raw material used in the manufacture of silicon wafers for the semiconductor industry. The process of converting metallurgical-grade silicon into purified silicon wafers involves several steps. Here are the key characteristics of metallic silicon powder used in this process:

Purity: Metallic silicon powder typically has a purity level of around 98-99%, with the remaining composition consisting of impurities like iron, aluminum, calcium, and other elements. The purification process is crucial to achieve the high purity required for semiconductor applications.

Particle Size: The particle size of metallic silicon powder can vary depending on the manufacturing process. In the semiconductor industry, a specific range of particle sizes is preferred to ensure uniformity and consistency during the melting and crystallization process.

Melting Point: The melting point of metallic silicon is around 1414°C (2577°F). This high melting point allows the silicon to be melted and then crystallized into ingots, which are subsequently sliced into wafers for semiconductor fabrication.
