    St. Albans, VT May 3rd, 2021 – The Board of Directors of Superior Technical Ceramics (“STC” or the “Company”), a middle-market leader in advanced ceramics and portfolio company of Artemis, the Boston-based Industrial Tech firm, announced today that James R. Callan has been appointed President and CEO, effective April 19th, 2021. Mr. Callan brings more than 30 years of proven advanced manufacturing leadership to STC.

    Mr. Callan’s appointment marks another milestone for STC, which recently announced the acquisition of IJ Research, a specialty ceramic bonding and sealing player based in Santa Ana, California. Since its founding over a century ago, STC has long been recognized as an innovator in advanced ceramic technologies. Since partnering with Artemis in late-2018, the Company has moved to bolster that leadership position – accelerating new material innovations, building out its technical sales and engineering organizations, adding new process capabilities, and focusing its technical partnership model on the most demanding OEM customers and applications in aerospace, defense, analytical instrumentation, and semiconductor.

    A respected leader throughout the Industrial Technology space, Mr. Callan brings to STC a demonstrated track record of leading teams and companies through similar transformations – including executive positions at Consolidated Aerospace Manufacturing, A.M. Castle & Company, and The Timken Company. Over 30 years and multiple companies, James executed on a broad swath of leadership mandates, from clear-eyed strategic planning to overseeing operational transformations to integrating add-on acquisitions for full value realization, both organic and inorganic.

    According to James Ward, Chair of the STC Board and Partner at Artemis, Mr. Callan did so by first focusing on building world-class teams and customer-obsessed, can do, cultures: “As the next CEO of STC, James’s track record and qualifications speak for themselves. However, it is James’s abiding sense of mission, team, courage, and accountability that made him the perfect fit to lead STC into its exciting next chapter of growth and innovation. Artemis and the STC Board are thrilled to welcome James to STC. And we are equally thrilled to provide STC – and its remarkable team, customers, and strategic partners -- a leader of James’s quality and conviction. It is a natural fit, and an exciting future for STC.”

    Mr. Callan holds an MBA in International Business from University of Dallas Graduate School, a BBA in Marketing and Business Management from Northwood University, and completed an executive program at UVA Darden School of Business. He is fluent in English as well as conversational in Spanish and Mandarin Chinese having spent time leading teams in Mexico and Singapore.

    Superior Technical Ceramics (STC), one of the country's most experienced technical ceramics manufacturers, announced the acquisition of IJ Research, a manufacturer specializing in sapphire-to- metal brazed hermetic assemblies based in Santa Ana, California. The acquisition closed on December 24th of last year.

    “We are delighted to add IJ Research to the portfolio,” said Peter Morten, former CEO of STC. “ Their brazing and sealing capabilities expand our technical capabilities for key customers and provide multiple opportunities for vertical integration.  Moreover, like us, they have earned a well-deserved reputation for working in markets that require complex and challenging materials solutions. These include the defense, aerospace, medical and analytical instrumentation industries, which are all growth markets. We’re excited by the many opportunities we see for synergies and enhanced customer relationships as we move ahead."

    IJ Research, Inc. is a manufacturing company specializing in applications that include electrical feedthroughs and opto-electronic windows, along with various sapphire-to-metal brazed hermetic assemblies.  The firm provides a broad range of services for customers with demanding engineering requirements, including conceptual design, research and development, materials selection consulting, and prototyping through to manufacturing. 

    “We are excited to be a part of STC,” said Dr. Rick Yoon, former CEO & owner of IJ Research.  “The firms are a natural fit in many ways, as we both share similar cultures, each with a deep respect for engineering talent, a nimble working style and a shared vision for customer-centric servicing. The fact that we share work with customers in many of the same markets illustrates the opportunities that now exist for integrated offerings and mutual growth."
