Polysilicon manufacturing start-up Hoku Materials has a supply agreement with Evonik Degussa for the purchase of trichlorosilane, a key process chemical. Hoku said it plans to use the TCS supplied by Evonik, together with TCS from other potential suppliers, to support the first phase of commercial production at its polysilicon facility in Pocatello, ID.
The agreement calls for Evonik to supply Hoku with a guaranteed quantity of TCS during the initial contract term of approximately one year. The polysilicon company will have the option to request quantities of the chemical in addition to the monthly guaranteed take or pay amount.
Regular deliveries are expected to begin in July, although Hoku has the option to request earlier shipments, as required. Hoku confirmed that it is using a limited quantity of the chemical already supplied by Evonik for Hoku’s reactor test demonstration this month, in addition to TCS supplied by another producer.
Financial details of the deal were not disclosed.
“Hoku is pleased to have established this relationship with Evonik,” said Scott Paul, president/CEO of parent company Hoku Corp. “Evonik is one of the world’s leading suppliers of TCS. Our interim use of high-quality TCS from Evonik will enable us to ramp up commercial production of polysilicon this summer before we complete the construction of our onsite TCS plant later this year.”
