PyroDelta's Capillary Casting Process Featured in IEEE Spectrum

Vancouver, BC — May 6, 2026 — Leads & Copy — First Tellurium Corp.'s subsidiary, PyroDelta Energy, has been featured in IEEE Spectrum for its innovative capillary casting process, which is expected to transform thermoelectric crystal manufacturing.

The article highlights PyroDelta's pioneering capillary casting process, an innovation poised to reshape the future of thermoelectric materials and energy harvesting. It emphasizes how the technology reduces materials waste by 60–80% and produces crystals with up to ten times greater durability compared to conventionally machined components. The ability to form curved or tubular geometries also enables new thermoelectric generator designs, including pipe‑integrated systems for data‑center cooling loops, automotive radiators, and aerospace applications.

Michael Abdelmaseh, Head Engineer at PyroDelta, expressed his pleasure at sharing the company's ideas with the global engineering community through IEEE Spectrum, which he regards as the premier publication for emerging engineering innovations.

Don Freschi, Technical Advisor to First Tellurium and CEO of Fenix Advanced Materials, sees the feature as validation of PyroDelta’s technology and processes, noting IEEE Spectrum's adherence to rigorous editorial standards.

Freschi added that PyroDelta’s thermoelectric technology is unique and will change how waste energy is harvested across various industries. He noted the patented technology can handle large temperature gradients while remaining intact and fully functional, unlike traditional thermoelectrics.

Tyrone Docherty, President and CEO of First Tellurium, noted the versatility of PyroDelta’s technology, stating that while the current focus is on heavy-lift drones, the technology can also capture waste heat and turn it into renewable energy in industries such as AI data centers.

Docherty also mentioned the recent Globe & Mail article about Michael and the capillary casting process, expressing his satisfaction with the increasing awareness of the technology.

PyroDelta’s technology is particularly relevant as AI‑driven data centers seek solutions to manage and reclaim unprecedented thermal loads. The thermoelectric generators can convert waste heat into usable electrical power, which can support data center sensors, monitoring systems, and other distributed electronics.

First Tellurium’s business model involves generating revenue and value through mineral discovery, project development, and the development of tellurium-based technologies.

PyroDelta Energy remains committed to advancing thermoelectric technology for a more efficient and sustainable energy future.
