HPQ-Silicon, PyroGenesis sign NDA for 4N Si samples

Mr. Bernard Tourillon of HPQ-Silicon reports


HPQ-Silicon Resources Inc. and PyroGenesis Canada Inc. have signed a non-disclosure agreement (NDA) with a world-leading high performance material company (HPMC) for the purposes of preparing 4N silicon (Si) material samples. HPQ-Silicon will make the dedicated samples using material produced by the Purevap quartz reduction reactor (QRR) pilot plant, which is scheduled to start at the end of Q1. For industry competitive reasons and in accordance with terms of the NDA, the identity of the HPMC and other parties involved must remain confidential; however, HPQ-Silicon can divulge that the 4N silicon material will be tested for usage as potential feedstock for the manufacturing of silicon nitride (Si3N4) ceramics.

4N silicon needed as feedstock to make silicon nitride (Si3N4) ceramics

In 2018, Apollon Solar advised HPQ-Silicon that silicon nitride was one of the specialty materials that needed 4N silicon in its manufacturing. Silicon nitride is a refractory material, meaning it is chemically inert and can resist extremely high temperatures. It is used in advanced high-tech materials to make robust components with very specific requirements as these advanced materials must be electrical insulators, resistant to wetting by non-ferrous metal melts, and able to withstand corrosive and high-wear environments, high mechanical stresses, and thermal shock. Most important, these properties must be maintained at high temperatures.

For example, in NASA's space shuttle project, silicon nitride spheres were used as low-friction ball bearings in the equipment, which supplied the main engines with cryogenic liquid hydrogen and liquid oxygen, the rocket's propellants. These bearings outperformed traditional equivalents, boasting lower friction, lighter weight, better longevity and less lubrication needed. Today, they can be found in more terrestrial settings, such as wind turbines, bicycles and high-end cars. Silicon nitride manufacturers are seeking ways to reduce powder processing costs to speed adoption of this remarkable material.

"We were approached by a representative of the high performance material company seeking samples of our 4N silicon material to test as feedstock to make silicon nitride ceramics. This is just one example of the many niche market applications that production from our Purevap QRR process can potentially supply," said Bernard Tourillon, president and chief executive officer of HPQ-Silicon. "High-purity silicon's (4N plus) potential is undeniable and generating serious industry interest, so our timing could not be better as this sample request from the HPMC confirms awareness of our unique silicon production capabilities at the highest enterprise levels across the world. Nonetheless, we are still in the early stages and will continue to apply the methodical approach that has put us in this position, with this sample request confirming the potential for new and exciting advances by HPQ in the high-purity silicon space."

About PyroGenesis Canada Inc.

PyroGenesis Canada, a high-tech company, is a leader in the design, development, manufacture and commercialization of advanced plasma processes and sustainable solutions that reduce greenhouse gases (GHGs) and are economically attractive alternatives to conventional dirty processes. PyroGenesis has created proprietary, patented and advanced plasma technologies that are being vetted and adopted by multiple multibillion-dollar industry leaders in three massive markets: iron ore pelletization, aluminum, waste management and additive manufacturing. With a team of experienced engineers, scientists and technicians working out of its Montreal office and its 3,800-square-metre and 2,940-square-metre R&D (research and development) and manufacturing facilities, PyroGenesis maintains its competitive advantage by remaining at the forefront of technology development and commercialization. The operations are ISO 9001:2015 and AS9100D certified, having been ISO (International Organization for Standardization) certified since 1997.

About HPQ-Silicon Resources Inc.

HPQ-Silicon Resources is a Quebec-based innovative silicon solution company that offers silica-based (SiO2) and silicon-based (Si) solutions and is developing a unique portfolio of high-value-added silicon products sought after by battery and electric vehicle manufacturers. Silicon, also known as silicon metal, is one of today's key strategic materials needed for the decarbonization of the economy and the renewable energy revolution (RER). However, silicon does not exist in its pure state and must be extracted from quartz (SiO2) in what has historically been a capital-intensive and energy-intensive process. With PyroGenesis Canada, HPQ-Silicon is developing the Purevap quartz reduction reactor (QRR), an innovative process (patent pending) that will permit the one-step transformation of quartz (SiO2) into high-purity silicon (Si) at reduced costs, energy input and carbon footprint that will propagate its considerable renewable energy potential. Through its 100-per-cent-owned subsidiary, HPQ Nano Silicon Powders Inc., the Purevap nanosilicon reactor (NSiR) is a new proprietary process that can use material produced by the QRR as feedstock to make a wide range of nanospherical/microspherical powders of different sizes and nanowires. Through its second 100-per-cent-owned subsidiary, HPQ Silica Polvere Inc., HPQ-Silicon is developing a new plasma-based process that will allows a direct quartz-to-fumed-silica transformation, removing the usage of hazardous chemical in the making of fumed silica and eliminating the hydrogen chloride gas (HCl) associated with its manufacturing.

HPQ-Silicon is also a technology development company interested in developing hydrogen-based ventures that could be complementary to the QRR efforts. Currently, HPQ-Silicon is evaluating two different approaches to reach this goal, those being:

  • Working with Swiss-based company EBH2 Systems SAS as it pertains to their EBH2's process to manufacture green hydrogen through electrolysis;
  • Developing the company's own processes of making hydrogen through hydrolysis of nanosilicon materials made by the company's Purevap NSiR.

We seek Safe Harbor.
