MONTREAL, Sept. 04, 2025 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ , OTCQB: HPQFF , FRA: O08 ), a technology company driving innovation in advanced materials and critical process development, is pleased to report that its subsidiary, HPQ Silica Polvere Inc. (“HSPI”) [1] , has successfully produced commercial-grade fumed silica during Test #6 of its proprietary Fumed Silica Reactor (“FSR”) pilot project.
The test, conducted by technology supplier PyroGenesis Inc. (TSX: PYR , OTCQX: PYRGF , FRA: 8PY1 ), achieved a surface area of 136 m²/g , a performance benchmark consistent with commercial specifications. The results were provided directly by a leading global fumed silica manufacturer with whom HPQ maintains a Letter of Intent (LOI).
“With Test #6, we achieved a core objective: demonstrating that our Fumed Silica Reactor can replicate lab-scale surface area results at pilot scale,” said Bernard Tourillon, President and CEO of HPQ Silicon Inc. and HPQ Silica Polvere Inc. “This is a pivotal validation of both the process and the product—confirming that we can now produce commercial-grade fumed silica in a single-step, scalable operation.”

Key Performance Gains from Test #6
Following the process optimizations made after Test #5, as disclosed in HPQ’s August 20, 2025, release , test #6 of HPQ’s Fumed Silica Reactor yielded critical advances in material performance:
- Surface area increased by 309% compared to the previous test, demonstrating significant process refinement.
- The material achieved a specific surface area of 136 m²/g, falling within HPQ’s internal lab-scale benchmark range of 135–185 m²/g [2] —a strong indicator of reproducibility at pilot scale.
- Surface area of 136 m 2 /g now meets the requirement for commercial grades 90 (75-105 m 2 /g) and 130 (105-155 m 2 /g), and enters the lower range of grade 150 fumed silica products which have a surface area range of 135-165 m 2 /g [3]
- Carbon-based impurities were eliminated, resulting in a cleaner and more industrially desirable product.
- Scanning Electron Microscope (SEM) analysis confirmed morphological features consistent with those of commercial-grade fumed silica, further validating the material's quality.
“Our next phase will focus on pushing surface area performance into the 200 m²/g + range, which represents the high-demand segment of the commercial market,” added Tourillon. “While there’s no certainty, we’ll reach that threshold in the immediate next test, having solved the most complex hurdles to get here, we believe the remaining challenges are manageable and that our pathway to commercialization remains strong.”
