(“PyroGenesis” or “the Company”) (TSX: PYR) (OTCQX: PYRGF) (FRA: 8PY1), the leader in ultra-high temperature processes and engineering innovation, and a plasma-based technology provider to heavy industry & defense, confirms, further to a recent press release from the Company’s client HPQ Silicon Inc. (“HPQ”), receipt by the Company of additional independent verification of its most recent test results for fumed silica produced by the fumed silica reactor (FSR). Specifically, a potential customer [press release dated July 9, 2024] who has been independently analyzing the various FSR test runs, has confirmed that the material produced during Test #7 meets established commercial benchmarks for fumed silica with a specific surface area (under BET analysis) of approximately 150 m²/g, while, more importantly, achieving the required viscosity for that commercial grade at the same time. Graph: surface area progression of fumed silica produced by the fumed silica reactor. “The results of test 7, and subsequent analysis and verification by two unrelated independent entities, confirm that the fumed silica reactor is now producing fumed silica at the important 150 commercial product grade,” said P. Peter Pascali, President and CEO of PyroGenesis. “As important is the fact that we have now replicated, at pilot scale, the results from our original lab-scale results for both viscosity and surface area of fumed silica. As some readers may recall, it was these initial findings that resulted in the interest exhibited by a global manufacturer of fumed silica, and with whom we have been working together to perfect the product. The question had always been, up to now, ‘…could we scale the results..?’ The viscosity results are particularly noteworthy, as it indicates that fumed silica produced at the pilot plant can be suitable for industrial applications including coatings, adhesives and sealants, inks, elastomers, and insulation binders where viscosity, often referred to as rheology effici...
