Silicon (Si)

Silicon (Si) is a semi-metal and one of the most useful elements to mankind. When ultrapure, it is solid; it has a blue-gray metallic sheen. Silicon is one of the most abundant elements on earth and is a semiconductor. Crystalline bulk silicon is inert but becomes more reactive at high temperatures.

Purity 98%-99.995%
Typical Applications

Silicon has wide uses as a semiconductor in solid-state devices in both computers and microelectronics. Silicon (Si) is important to the metals industry as it is used to deoxidize steel and make alloys, including aluminum-silicon and ferrosilicon. Silicon is also used to make silicones.

Sustainable Qualities

Amorphous Silicon is considered sustainable due to its non-toxic nature, abundance in the earth’s crust, and its ability to be easily recycled. As a bio-based material, it can be derived from renewable sources such as agricultural waste or biomass. It is widely used in the solar cell industry, offering an alternative to traditional crystalline silicon with lower production costs and higher energy conversion efficiency. Additionally, Amorphous Silicon thin films can be deposited on flexible substrates, enabling the development of lightweight and portable solar cells.

In terms of contributing to the circular economy, Amorphous Silicon can be recycled through various methods, including chemical treatments and thermal processes, which recover its valuable components and prevent waste. Its sustainable nature, low environmental impact, and recyclability make it an attractive material for sustainable energy applications.
