[{"type":"text","content":"Independent Analysis Confirms HPQ Fumed Silica Reactor Produces Commercial-Grade Material at Pilot ScaleHPQ achieves a key milestone toward commercial production, producing commercial-grade fumed silica with superior surface area and purity in a single step at pilot scale\n\n\n\n MONTREAL, Nov. 12, 2025 (GLOBE NEWSWIRE) --\n \n\n HPQ Silicon Inc.\n \n\n (“HPQ” or the “Company”) (“HPQ” or the “Company”) (TSX-V:\n \n HPQ\n \n , OTCQB:\n \n HPQFF\n \n , FRA:\n \n O08\n \n ), a technology company driving innovation in advanced materials and critical process development, is pleased to announce that independent laboratory analysis\n \n [1]\n \n of material produced during Test #7 of its proprietary Fumed Silica Reactor (FSR) pilot plant has confirmed the production of commercial-grade fumed silica.\n \n\n This achievement validates the scalability and performance of HPQ Silica Polvere Inc.’s (HSPI)\n \n [2]\n \n unique plasma-based process. It confirms that the technology can produce hydrophilic fumed silica directly from quartz, without the use of chlorosilanes or the production of hazardous by-products.\n \n\n\n Pilot Plant Results Exceed Previous Tests – Validate Commercial Quality of Material\n \n\n\n Independent laboratory testing of material from the most recent pilot-scale run produced the following results:\n \n\n\n\n Specific Surface Area (BET)\n \n : 168.44 to 191.17 m²/g\n \n (up from 136 m²/g achieved during Test #6, a 20 to 40 % improvement in Surface Area.)\n \n\n\n\n\n Product Purity (ICP-MS)\n \n : 99.74 – 99.83 percent\n \n (up from 97.92 percent in Test #6 and above the 99% purity commercial baseline)\n \n\n\n\n\n XRD Analysis\n \n : Fully amorphous powder, representative of true fumed silica structure.\n \n\n\n\n These results confirm HSPI’s ability to replicate the lab-scale data announced in\n \n November 2023\n \n (135 – 185 m²/g range with 99% purity) and also demonstrate measurable improvements in both purity and performance consistency. The achieved range of up to 191 m²/g and 99.8% purity positions the material squarely within the upper end of commercial specifications typically targeted by leading fumed silica producers.\n \n\n\n “Replicating and surpassing lab-scale results at a commercial p...
