The findings are significant in that they demonstrate the success of bench scale test work in scaling up the process of converting low purity feedstock into higher purity silicon metal.\n\n\n \nBernard Tourillon, Chairman and CEO of HPQ-Silicon stated, \"Demonstrating the scalability, at lab scale, of the PUREVAPtm QRR process in a repeatable and predictable manner while obtaining consistent purity results of 99.9+% (3N+)1 Si using 98.14% or less (1N) SiO2 feedstock, represents yet another important technical milestones in in our progress toward production of High Purity Silicon metal. At this stage of our development, we have passed the critical milestones of consistently increasing sample size and now work will focus on improving the purity of the final product. This 'iterative' approach of incrementally increasing size, and purity step by step will continue and has so far been highly successful\".\n\n\n \nTESTING CONFIRMS LAB SCALE SCALABILITY OF PUREVAP(TM) QRR PROCESS \n\n\n \nThe report confirms the scalability of the Process, explaining that in order to improve the yield of High Purity Silicon Metal (99.9+% Si) produced per batch, the lab-scale PUREVAPtm QRR reactor was successfully modified and capacity scaled up by a factor of 3 (300%). As a result, yield went from less than 0.1 g to 8.8 g (test #32), an increase of approximately 9,000% (hundredfold).\n\n\n \nOf significant interest is the fact that all these results were obtained using lower purity feedstock (98.14% or less SiO2) than used by the Silicon Metal industry to produce Metallurgical Grade Silicon Metal (98.5% Si). Moreover, the results suggest that HPQ PUREVAP(TM) QRR PROCESS is the only process in the world that can systematically produce Silicon Metal of a purity above 3N+ (99.9+% Si) from sub-standard purity feed quartz.\n\n\n \n\...
