HPQ Gen1 Nano Silicon Reactor Exceeds Phase 1 Production Rate Target By 67%

Production Rate: Key To Commercial Viability Of Nano Silicon Materials

MONTREAL, Canada, April 22nd, 2021 — Innovative silicon solutions provider HPQ Silicon Resources Inc. (“HPQ” or the “Company”) (TSX-V: HPQ; FWB: UGE; OTCQX :HPQFF), an innovative silicon solutions company, through its wholly – owned subsidiary HPQ Nano Silicon Powders inc (“HPQ NANO”), is pleased to update its shareholders on the recent milestones achieved by the Gen1 PUREVAP™ Nano Silicon Reactor (“NSiR”) process validation and optimization tests.

The ongoing tests are conducted by the technology provider, PyroGenesis Canada Inc. (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY), as per the agreement announced on August 18th, 2020.


The Gen1 PUREVAP™ NSiR test bed is a batch process system with an originally targeted design output production rate of 30 kg/month of nano silicon powders. The Gen1 NSiR recently achieved a production rate equivalent to 50 kg/month of nano powders, a result that exceeded the design output by 67%. The significance of this is twofold:

  1. Expectation of greater throughput than originally planned for the commercial tests,
  2. Expectation of reduced unit costs and production costs as a result of increased throughput.


NSiR test bed work results to date leads us to conclude that the Gen2 NSiR semi-continuous proof of commercial scalability system will be able to have an ultimate monthly increased production rate of 500 kg/month (or about 6 MT/year) of nano silicon powders or nanowires. This is substantially greater than the originally stated 300 kg/month (or about 3,5 MT/year) mentioned in our press release dated August 18th, 2020.

“HPQ NANO Gen1 PUREVAP™ NSiR testing program is moving forward, and we are very pleased that with each test completed, we are reaching new operational milestones exceeding our original expectations. With these new results, HPQ NANO is confident that it can achieve the desired nano silicon material for batteries which will be cost-competitive with graphite”, said Bernard Tourillon, President and CEO HPQ Silicon. “With the use of silicon in batteries anodes expected to increase from less than 5% today to over 30% by 20301, HPQ NANO is very well positioned to become the nano silicon provider of choice for the industry. HPQ’s silicon R&D consortium continues to strive for cost-effective ways of increasing the silicon contained in batteries.”


The ongoing tests are crucial as they allow PyroGenesis to progress on the project while identifying and resolving normal R&D issues systematically. The main segments of the ongoing process validation and optimization tests can be summarized as follows:

  1. Validation that the system can produce < 150nm nano materials,
  2. Validation that the system can reach its design production parameters, and
  3. Production of qualified samples.

The ongoing tests have achieved significant results and have generated extremely valuable information that will be applied to future developments. Despite the difficulties of operating under the stress of COVID-19, PyroGenesis’ team has achieved outstanding results while maintaining strict and new operating procedures to protect all of its staff from the effects of the virus. In addition, several unexpected issues occurred during the conversion of the Gen2 PUREVAP™ QRR reactor into the Gen1 PUREVAP™ NSiR, which modelling and computer simulation did not foresee. These were overcome by the professional team at PyroGenesis. The results also demonstrated that our PUREVAP™ QRR has a unique ability to produce a low-cost HPQ battery-grade silicon for less than commercially available metallurgical grade silicon.

Since the start of the testing program, we have demonstrated the following positive results from the PUREVAP™ NSiR process:

  1. Production of nano silicon powders of less than 150 nm, the threshold above which silicon fracturing occurs.
    1. Further efforts will focus on improved measures and control the size distribution of our material, a critical criterion for battery manufacturers.
  2. Production rate achieved exceeded the original goal.
    1. Continuous process improvements to further increase the production capacity, and thereby reducing future commercial production cost.

Once the final equipment modifications are completed, the goal of the program will be to produce qualified samples which will then be tested by a third-party, the Institut National de Recherche Scientifique (INRS), and subsequently to awaiting battery manufacturers and automobile manufacturers.

“As experts in successfully taking lab-scale concepts to commercialization, we can confirm that these results not only demonstrate that we are on the right track but that the project is progressing as expected.” said P. Peter Pascali, President and CEO of PyroGenesis. “It is even more exciting when one considers the impact this could have on addressing the challenges facing the EV battery space. We are proud to be using our plasma expertise in support of, and advancing, green initiatives.”
