PyroGenesis confirms pilot-grade fumed silica quality

Executive Summary

• PyroGenesis confirms that third-party Scanning Electron Microscopy (SEM) analysis of Phase 1 Test No. 5 material from its Fumed Silica Reactor (FSR) validates that the pilot-scale product morphology is consistent with commercial-grade fumed silica.
• The analysis supports key technical metrics previously announced, showing that the pilot plant successfully reproduces lab-scale quality at pilot volumes.
• Phase 2 trials are scheduled for August to further validate material quality and prepare for commercial qualification, with a focus on process stability and yield enhancement.

Key Details

• SEM Analysis Results:
  • Phase 1 Test No. 5 material matches lab-scale fumed silica results with improved particle structure.
  • SEM images exhibit morphology and structure consistent with commercial-grade fumed silica.
• BET Analysis Data:
  • Brunauer-Emmett-Teller (BET) analysis indicates that reactor enhancements are successfully closing the gap between pilot-run and lab-scale surface area performance.
  • Data confirms the specific surface area metrics are aligning with commercial expectations.
• Project Timeline & Next Steps:
  • Phase 2 trials are scheduled for August 2025.
  • Objectives for Phase 2 include further validating material quality and preparing for commercial qualification.
  • Remaining engineering efforts will focus on process stability, yield enhancement, and further surface area refinements.
• Company Structure & Context:
  • PyroGenesis is developing the FSR pilot plant for HPQ Polvere Inc., a subsidiary of HPQ Silicon Inc.
  • PyroGenesis holds a 50% interest in Polvere.
  • PyroGenesis has an exclusive arrangement to be the sole supplier of equipment relating to any commercialization of this new process.
  • Fumed silica is described as a widely used industrial material in products ranging from cosmetics and pharmaceuticals to batteries and construction materials.

Notable Quotes

• "With the SEM imagery validation of test No. 5, we have greater confidence that the FSR consistently reproduces lab-scale quality at pilot volumes," said P. Peter Pascali, president and chief executive officer of PyroGenesis. "Remaining engineering efforts will now focus on process stability, yield enhancement and further surface area refinements -- all critical for phase 2, which is fast approaching."
