Synthetic-Oxides to sell limited Nanoporous Ferric Oxide samples on eBay in July

Synthetic-Oxides LLC says it will start offering a very limited quantity of Nanoporous Ferric Oxide samples on eBay in mid-to-late July 2026 under the Accel-O-Rust name. The launch targets battery, supercapacitor and industrial developers looking for tuned grain sizes, surface areas and dispersion properties.

Why it matters: - Synthetic-Oxides LLC is moving a niche material into a public marketplace, which could give battery, supercapacitor and industrial engineers access to sample quantities without a custom procurement cycle. - The company says performance-tuned Nanoporous Ferric Oxide could matter for batteries, supercapacitors, biomed, filtration, ordnance, propulsion, remediation, sensors and other industrial uses.

What happened: - Synthetic-Oxides LLC said it will begin selling a very limited quantity of Nanoporous Ferric Oxide samples on eBay in mid-to-late July 2026. - The material will be sold under the tradename Accel-O-Rust. - The company said a separate press release will follow when the Synthetic-Oxides eBay store goes live.

The details: - Three grades are planned: TAN Grade, RED Grade and BROWN Grade. - TAN Grade has the smallest grain sizes and surface areas. - RED Grade has medium grain sizes and surface areas. - BROWN Grade has the largest grain sizes and surface areas. - As of the press release date, about 20 TAN Grade samples and about 40 RED Grade samples were available for sale. - Another about 30 samples, with grade still to be determined, were expected to come online later that week. - The company says NFO can be tailored to specific particle sizes and surface areas for different applications. - Synthetic-Oxides says full technical disclosure, including about 75 pages of independent lab test results, is available at the company's technical disclosure. - The release says nanoscale and nanoporous are not the same term. - Nanoscale refers to grain size. - Nanoporous refers to particle architecture. - The release identifies two types of nanoporous ferric oxide powders. - Nanoscale nanoporous ferric oxide has particle grain sizes in the 200-350 nm range and is synthesized in single-gram lab-scale batches using the Aero Sol-Gel Synthesis Method. - The Aero Sol-Gel Synthesis Method is referenced in this technical paper. - Micron nanoporous ferric oxide has grain sizes about 50 times larger than Aero Sol-Gel particles and is synthesized in about 750 gram batch sizes using Synthetic-Oxides' proprietary Hybrid Synthesis Method. - The company says the Hybrid Synthesis Method has been refined over 16 years of self-funded R&D. - In 2024, Accel-O-Rust demonstrated near-uniform particle dispersion in a silicone composite after about 2 minutes of simple mechanical stirring. - Nikon Metrology Helical CT Scans independently verified that dispersion result. - Tim Rolf is listed with Synthetic-Oxides LLC, along with a phone number: +1 202-716-9400. - The release also includes the company's LinkedIn profile as social media.

Between the lines: - The launch appears designed to create an early market for a highly specialized material by selling small sample lots first, rather than waiting for full-scale distribution. - The emphasis on customizable grain size, surface area and dispersion suggests the company is trying to differentiate the material on application-specific performance, not commodity pricing. - Some performance claims in the release are forward-looking or comparative and should be read as the company's positioning rather than independently established market conclusions.

What's next: - Synthetic-Oxides said more samples are expected later in the week, with the grade still to be determined. - The company said it will provide another update once its eBay store is live. - Engineers and developers interested in the material can review the technical disclosure and lab results before the planned July sales window.

The bottom line: - Synthetic-Oxides is preparing a limited eBay launch for a customizable nanoporous ferric oxide line, betting that application-specific materials can find demand across energy storage and industrial markets.
