Material produced during this test has been delivered for analysis to two third-party laboratories. One is a global fumed silica manufacturer operating under an active Letter of Intent (LOI) as announced in our\n \n July 9, 2024, release\n \n , and the other is a university laboratory.\n \n\n\n\n\n Material produced during test 6 by the Fumed Silica Reactor (Image provided by PyroGenesis).\n \n\n\n\n\n Operational Highlights from Test #6\n \n\n\n The process improvements implemented between Test #5 and Test #6 yielded the following key operational gains:\n \n\n\n\n Reduced Start-Up Time\n \n : The time required to bring the FSR to optimal operating conditions was reduced by 50 percent, potentially improving overall process efficiency\n \n\n\n Increased Throughput\n \n : The number of semi-continuous batches doubled relative to the previous test, while total material output increased fivefold.\n \n\n\n Demonstrated Scalability\n \n : The performance of Test #6 reinforces confidence in the scalability of HPQ’s proprietary FSR process and its future transition to commercial-scale operations.\n \n\n\n\n\n “These operational improvements represent a meaningful advancement in the development of our Fumed Silica Reactor technology,”\n \n said Bernard Tourillon, President and CEO of HPQ Silicon Inc. and HPQ Silica Polvere Inc.\n \n ...
