Evonik to to build North America’s first plant for ultra-pure colloidal silica

The US$ 7.9 million plant expected to come onstream in 2024 in Weston, Michigan, USA

Evonik, one of the world’s leading specialty chemicals companies, is building a new plant to produce ultra-high purity colloidal silica at its site in Weston, Michigan, USA which is expected to generate a total capital spending of $7.9 million in 2023 and 2024.

The plant, which is expected to come onstream in 2024, will be the first of its kind in North America. Colloidal silica is an important raw material for the electronics and semiconductor industries, whose growth is driven by the global demand for microchips and digital products.

The new plant will make Evonik one of the only players in the market that can reliably produce the colloidal silica required for the chemical mechanical planarization (CMP), a process step in microchip production in the necessary quality and purity. Evonik’s colloidal silica, which is marketed under the IDISIL brand, is characterized by its ultra-high purity and particularly narrow particle size distribution.

“The new plant makes an important contribution to the strategic development of our portfolio,” says Peter Friesenhahn, head of Evonik’s Silanes business line. “We are strengthening our offering for attractive, technology-driven growth markets and positioning ourselves as an innovation partner for our customers.”

Evonik is already a major supplier of ultra-pure tetrachlorosilane and other silanes for the semiconductor and electronics industry, and has a global network of production facilities and scientists in this field. “It will enable us to offer our customers additional supply options and even better security of supply in the future,” says Christian Edlinger, head of the Americas region in the Silanes business line. Until now, companies producing in the Americas have often had to rely on imports from Asia.

With the support of a $900,000 Michigan Business Development Program performance-based grant, the expansion will not only strengthen Evonik’s presence in Michigan, but also create new job opportunities in the region. “We’re thrilled to celebrate this expansion by Evonik, helping to keep us at the forefront of the global semiconductor industry,” said Michigan Governor Gretchen Whitmer.

“Team Michigan is proud to bring home this win and build on our leadership in the semiconductor supply chain,” said Quentin L. Messer, Jr., CEO of the Michigan Economic Development Corporation. “We are grateful for Evonik’s vote of confidence in our state.”
