HPQ Silicon GEN3 QRR Pilot Plant Produces 3N+ Silicon (99.92% Si) in a Single Step

Article content material

MONTREAL, June 01, 2023 (GLOBE NEWSWIRE) — HPQ Silicon Inc. (“HPQ” or the “Firm”) (TSX-V: HPQ) (OTCQX: HPQFF) (FRA: O08), a expertise firm specializing in inexperienced engineering processes for silica and silicon materials manufacturing, pronounces the profitable validation of a vital milestone that demonstrates the capabilities of our proprietary expertise, the PUREVAP^TM Quartz Discount Reactor (QRR) course of. Our accomplishment is that now we have produced Silicon with a purity exceeding 3N+ in a single step.

This validation follows an intensive overview of take a look at #5 outcomes from the continuing GEN3 pilot plant program performed by expertise supplier PyroGenesis Canada Inc. (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY) (Pyrogenesis).

The outcomes are additionally extremely promising as a result of they affirm the potential of the QRR course of to scale back the money price of silicon metallic manufacturing via a single-step course of and by reducing the feedstock requirement.

“These developments mark a milestone for HPQ Silicon and spotlight the effectiveness of the PUREVAP^TM QRR course of in modernizing the manufacturing of high-purity Silicon whereas concurrently driving down manufacturing prices,” mentioned Bernard Tourillon, President & CEO of HPQ Silicon. “HPQ, with associate Pyrogenesis, is regularly advancing its new QRR expertise. These current outcomes display extra optimistic progress within the efforts to create a brand new, low-cost course of to fabricate of excessive purity Silicon. The prevailing processes have remained largely unchanged for the previous century.”

PRODUCED 3N+ PURITY SILICON OR BATTERY-GRADE SILICON

Pyrogenesis completely assessed the Silicon materials generated throughout assessments #4 and #5 within the sequence. The samples have been analyzed utilizing ICP-MS Silicon Bulk Pattern Evaluation at Air Liquide Electronics (Balazs NanoAnalysis).

In take a look at #4, the outcomes revealed a median silicon purity (%) surpassing 99.8%. This achievement signifies a noteworthy enhancement in comparison with the earlier finest outcomes of 99.6% Si, as announced on March 16th.

Nevertheless, it’s the consequence of take a look at #5 that’s noteworthy.

Throughout take a look at #5, we achieved a median silicon purity (%) of 99.92% throughout two separate assessments. This consequence validates the potential of the QRR course of to surpass the minimal purity requirement of 3N, particularly for battery-grade silicon.

The achievement strikes ahead HPQ in its purpose of manufacturing high-purity silicon for battery and different high-value functions with the QRR.

QRR PROCESS: UNLOCKING A REDUCTION IN CASH COSTS FOR SILICON PRODUCTION

Conventionally, the manufacturing yield of metallurgical grade silicon (1-2N purity) ranges from 80 to 90% [1]. Nevertheless, when conventional vegetation implement optimized processes to supply larger purity silicon (2-3N), manufacturing yields are lowered to between 50 and 60% [2].

Our modern PUREVAP^TM QRR reactor, with its distinctive enclosed design, has the potential to realize a conversion effectivity exceeding 75% whereas constantly sustaining a excessive purity degree of 3N+ and extra.

This may allow us to supply one unit of silicon utilizing fewer items of feedstock, probably leading to a larger than 25% discount in feedstock utilization [3]. If profitable, this might present HPQ with an extra price benefit in comparison with conventional strategies.

As a part of our program’s goal to optimize feedstock utilization within the QRR course of, we’re delighted to report that take a look at #5 demonstrated this progress. The conversion effectivity of the method reached 20%, a four-fold enchancment in comparison with assessments #1 via #4.

“Outcomes so far display that we’re steadily progressing in direction of attaining a conversion effectivity of 75%, which can symbolize a leap ahead in high-purity silicon manufacturing, offering HPQ with financial benefits and course of effectivity throughout the silicon business,” added Mr. Tourillon. “We take nice delight within the efforts of the workforce at PyroGenesis and our position on this distinctive alternative and its potential for transformative impression.”

FILING OF NEW QRR PROCESS PATENT AND SHARES FOR DEBT SETTLEMENT

HPQ Silicon is happy to announce that it has entered into an settlement to accumulate all rights held by the inventors of a brand new PUREVAP^TM QRR provisional patent utility associated to enchancment of the Purity of the Silicon materials produce by the QRR by one (1) N. Virtually this invention will enable us to extend the purity of our Silicon from the 99.92% already achieved to 99.992%

This contract stems from negotiations between the events and the debt outcomes from the French laws stipulating that inventors of a patent are entitled to obtain remuneration for his or her work. That consideration was payable by the patent proprietor and have become a debt affecting the patent.

HPQ, to turn into the proprietor and purchase all of the rights in a transparent patent, negotiated the cost of the debt and agreed with the inventors that the debt within the quantity of $ 88,560 might be settled via the issuance by the corporate of 432,000 Items. The cost shall be made, in two phases, being 144,000 Items to every of the three inventors.

Every Unit will consist of 1 (1) widespread share of the Firm and one (1) warrant to buy one (1) further widespread share of the Firm at an train worth of $ 0.27 for a interval of two (2) years after the deadline of the transaction. The primary concern of 72,000 items to every of the inventors might be made on the date the Firm receives TSX Enterprise Trade approval. The second concern of 72,000 Items might be made to every of the inventors on the time of the worldwide submitting of the patent. This transaction is topic to TSX Enterprise Trade and regulatory approval.
