Sintx Technologies, Inc.

Sintx Technologies, Inc. was founded in 1995 in Boulder, Colorado, emerging from material science research at Battelle Memorial Institute. The company focused on developing advanced silicon nitride ceramics, a specialty material with high strength, thermal resistance, and biocompatibility. The strategy centered on licensing and scaling silicon nitride into three verticals: medical implants (artificial joints, spinal fusion devices) under the Amedica brand, armor products for military and commercial vehicles, and industrial components for renewable energy systems. Confirmed customers include Zimmer Biomet for medical ceramics and the US Department of Defense for armor applications. The firm employed roughly 58 staff as of 2022 and maintained a single headquarters in Boulder. In 2022, Sintx sold its Amedica medical implant business to Glantar GmbH, an event that reshaped the company's revenue profile toward the armor and industrial segments. Sintx's structural differentiator is its material platform approach: rather than competing as a standalone medical device or defense contractor, it licenses and co-develops a single proprietary ceramic across sectors. This model reduces capital intensity but requires sustained R&D and regulatory approvals.
