Sintx Technologies, Inc. provided revenue guidance for the third quarter and fourth quarter of 2021. Estimated revenue in third quarter of 2021 was approximately $240,000 which is more than the revenue in each of first quarter and second quarter of 2021.

The company anticipates new revenue sources in fourth quarter of 2021 with several open prototype orders expect to fill with advanced silicon nitride for separate aerospace engine and rocket components, FleX SN powder for antipathogenic fabric, and an industrial boron carbide application.
