Independent Analysis Confirms HPQ Fumed Silica Reactor Produces Commercial-Grade Material at Pilot Scale
Executive Summary
- Independent laboratory analysis confirms that material from Test #7 of HPQ Silicon’s proprietary Fumed Silica Reactor (FSR) pilot plant meets commercial‑grade specifications (BET surface area up to 191 m²/g; purity 99.74–99.83%).
- Results represent a 20‑40 % improvement in specific surface area and a jump from ~98 % to >99 % purity versus the previous test, positioning the product at the high end of market specifications.
- The company will now move toward full‑capacity operation (50 t/yr) and begin distributing sample batches under NDAs to potential industrial partners, advancing the commercialization stage of the FSR program.
Key Details
- Test #7 Material Quality
- Specific Surface Area (BET): 168.44 – 191.17 m²/g (up from 136 m²/g in Test #6).
- Product Purity (ICP‑MS): 99.74 % – 99.83 % (up from 97.92 % in Test #6; exceeds the 99 % commercial baseline).
-
XRD Analysis: Fully amorphous powder, confirming true fumed silica structure.
-
Comparative Performance
- Surface‑area improvement of 20–40 % versus Test #6.
-
Purity increase of ~2 percentage points, surpassing the 99 % commercial benchmark.
-
Technology Highlights
- Plasma‑based single‑step process uses quartz (SiO₂) as sole feedstock – no chlorosilanes, no HCl by‑products.
-
Energy consumption up to 87 % lower than conventional routes; CO₂‑equivalent emissions reduced by ~84 %.
-
Pilot Plant Scale
- Facility is 20× larger than the original lab‑scale unit, designed for continuous operation and full‑scale process optimisation.
-
Planned ramp‑up to design capacity of 50 tonnes per year after optimization of surface area consistency near 200 m²/g.
-
Next Steps
- Initiate optimisation phase to maintain ~200 m²/g surface area at pilot scale.
- Distribute sample batches under NDAs to potential partners in coatings, polymers, and advanced materials sectors.
-
Advance commercial discussions and begin planning a dedicated production site (commercialisation stage).
-
Market Context
- Global fumed‑silica market projected > US$2.57 billion by 2034, driven by coatings, sealants, automotive, and lithium‑ion battery applications.
