PyroDelta to Produce Bismuth Telluride Crystals for Thermoelectric Manufacturing

Vancouver, BC — February 12, 2026 — Leads & Copy —

First Tellurium Corp.'s majority-owned subsidiary, PyroDelta Energy Corp., will produce and sell high-end bismuth telluride crystals for thermoelectric manufacturing. The Florida-based facility utilizes PyroDelta’s Capillary Casting process to build custom-designed crystals that are free of defects, highly conductive, and more robust than current market offerings.

According to PyroDelta Head Engineer Michael Abdelmaseh, the company is the only one offering bismuth telluride crystals with this level of quality and flexibility to the thermoelectric industry. He added that their proprietary process resolves long-standing issues and constraints, including supply vulnerabilities from China, for manufacturers of thermoelectric devices in North America and beyond and that he is confident their crystals will set a new standard for the industry.

PyroDelta sources its raw materials, including high-purity refined tellurium and bismuth, from reliable North American sources. This resolves supply concerns related to import restrictions and shortages.

Telluride bismuth crystals, a key component for most thermoelectric devices, primarily come from China. They are built using the Bridgman Process, which leaves inherent defects in crystal alignment, resulting in long-standing inefficiencies for thermoelectric devices. Additionally, manufacturers must then endure a complicated, multi-step process to incorporate the crystals into their devices.

Abdelmaseh said that in the thermoelectric industry, there has been a compromise and inefficiency that they have always been told to accept, but not anymore. He said that their process allows them to grow far more robust crystals, then mold them into any shape—simple or complex—that a manufacturer requires and that they are the only crystal manufacturer able to provide these advantages.

He added that there is no cutting, no soldering, and no misalignment of crystals, allowing them to deliver the highest conductivity with the least waste. Their product also has a much lower resistivity to electric current, lower than any other crystals available on the market.

Abdelmaseh also stated that these advantages will save manufacturers money and open new applications for them. He said that they are no longer limited in their designs of thermoelectric devices, and their product will result in a whole new standard of quality and durability and that they have created the first economical, and readily available, modules that can withstand very high temperature extremes.

The Capillary Casting process has allowed PyroDelta to create the thermoelectric industry’s first practical and economical thermoelectric tubes. These devices harness waste heat from hot liquid and open many new markets, including AI and crypto mining data centers. Prototype thermoelectric tubular radiators have demonstrated the ability to harness waste heat from combustion engines and replace power-draining alternators.

Abdelmaseh said that the industry has tried to create efficient and practical tubes for many years, and now, with the Capillary Casting process, they have achieved that milestone. He added that any industry that produces hot liquid and needs cooling could benefit from their tubular generators, and AI and crypto mining data centers offer the biggest market at this time.

According to the release, another major market for PyroDelta’s conventional generators is solar power, with the devices being able to generate power from temperature differentials, whether hot or cold, on solar panels during low-sunlight days or even at night.

First Tellurium President and CEO Tyrone Docherty said that all of their research and development has been based on careful, patient science and testing for thermoelectric technology and that, as a result, PyroDelta has built the most effective, and cost-effective, devices on the market today. He added that to date, they have focused on putting their test devices in high value applications to ensure the technology’s viability.

PyroDelta has conducted a pilot program for supplying supplemental power to high-payload drones and has entered the U.S. Defense Department DARPA Lift Challenge competition, which will take place later in 2026. Abdelmaseh has led a team designing and building a drone that will lift at least twice its weight, which is the minimum standard to enter the competition. After entering the competition, PyroDelta received numerous offers to collaborate with other companies. However, Abdelmaseh has chosen to remain independent with its entry.

Docherty encourages shareholders and anyone in the thermoelectric industry to view the video to understand the implications of what PyroDelta has accomplished and why they’re so excited about it.
