Vice President of Business Development

“Silicon nitride is among the most advanced ceramic materials”, said Dr. Sonny Bal, Chairman and CEO of SINTX Technologies, “with applications across many industries. In addition to being approved for highly-demanding medical device applications, our formulation of silicon nitride has been characterized, validated, and tested extensively through a robust R&D program, and is fully competitive with industrial formulations required, for example, by the aerospace and defense industries. With the addition of Don, SINTX is well-positioned to focus on markets outside medical devices.”

“As SINTX explores new sources of OEM revenue and new partnerships inside and outside of health care, Don’s extensive background and experience in technical ceramics and business development are particularly relevant. In addition, Don has a proven track record of securing federal, state, and local funds in support of technology development; these skills will help SINTX continue a strategic pivot toward positioning its silicon nitride and related ceramic technologies for a broad range of medical and non-medical applications,” added Dr. Bal.

“I am thrilled to be part of the SINTX team”, said Mr. Bray. “My entire career has been spent in the advanced materials industry and I look forward to continuing that work in helping SINTX grow. They have a strong technology and manufacturing suite with many potential applications.”
