Coretec partners with Evonik to produce cyclohexasilane

By Scott Jenkins |

The Coretec Group Inc. (Ann Arbor, Mich.; www.thecoretecgroup.com) recently entered a supply partnership with specialty chemical company Evonik Industries AG (Essen, Germany; www.evonik.com) in which Evonik will produce cyclohexasilane (CHS; Si6 H12) for application development using intellectual property developed by Coretec. Coretec has developed a proprietary process for synthesizing CHS, a precursor of pure silicon.

Under the agreement, Evonik will produce 50-g samples of CHS by the end of 2020 for use by industrial customers in the development of silicon applications, such as Si quantum dots for next-generation (specific-frequency) LED lights, Si anodes for Li-ion batteries and low-power semiconductor computer chips.

Coretec CEO Michael Kraft notes that the company’s new process for CHS synthesis enables safe and low-cost production of CHS. Users can now take advantage of CHS’s unique properties, such as making high-purity amorphous Si at low temperatures. The physical properties of amorphous Si differ from crystalline Si, and are critical to the use of Si in quantum dots and other applications, he says.

Further, CHS is a liquid at ambient temperature and pressure, and allows the delivery of high-purity silicon to various manufactured products in a liquid form, and at much lower temperatures than would be required for gas-based plasma-deposition of Si. This reduces manufacturing costs and may eliminate certain manufacturing steps in making Si-containing technology products, Kraft says.

Coretec has filed for patents on the intellectual property associated with the new CHS synthesis process, which differs from a previous process under development by Coretec, which could not be scaled effectively (Chem. Eng., September 2016, p. 10).
