HPQ Silicon announces validation of milestones in HPQ PUREVAPE Gen3 testing

HPQ Silicon updates shareholders on the successful silicon pour. Subsequent to Sept 28th release, PyroGenesis Canada, the project’s technology provider, informed HPQ that the enhancements made to improve liquid silicon fluidity at the Gen3 QRR reactor’s base in September 2023 played a pivotal role in successfully achieving the final critical milestones, completing a successful silicon pour. As a result, the work completed has now successfully validated 100% of the project’s critical milestones, which include: achieving 99.5% Silicon purity from the outset, a level that exceeds the best commercially available purity threshold. Scaling up production by 2,500X from PUREVAPTM Gen2 QRR. Demonstrating the semi-continuous batch production capability of the reactor. Completing a successful silicon pour. Achieving one-step production of 3N+ Silicon or battery-grade Silicon. Production of silicon using 25% less feedstock than conventional carbothermic processes that use a ratio of 6 tonnes of raw materials to produce 1 ton of metallurgical grade silicon.
