The Carbon Conversion Platform
Engineered for scale, purity, and zero-effluent synthesis.
Achieving the theoretical limits of 2D carbon nanomaterials in the lab is established science; the challenge is commercial reproducibility. Our in-house reactor platform converts carbon precursors into industrial-grade Few-Layer Graphene (FLG) and Graphene Oxide (GO) through a closed-loop, reusable cartridge process.
Manufacturing Architecture
How our process works.
A simplified look at our carbon conversion platform. We guide carbon precursor materials through a 6-stage closed-loop sequence, refining raw inputs into certified two-dimensional structures.
Feedstock Input
Our synthesis begins with precisely calibrated carbonaceous compound precursor materials. We enforce strict structural and purity baselines prior to thermal loading, eliminating sulfur, heavy metals, and moisture before any conversion occurs.
This is a simplified overview for general understanding. Detailed reactor engineering and process specifications remain proprietary and patent-pending.
Process Economics & Integrity
Direct synthesis vs. legacy chemical methods.
Conventional graphene manufacturing has relied on 60-year-old chemical oxidation routes (Hummer's Method) that require metric tonnes of hazardous acids and produce heavy structural defects. We engineered our closed-loop reactor platform to eliminate liquid effluent while preserving pristine carbon bonds.
High Effluent, High Defect Density
- •Hazardous Acid Runoff: Generates metric tonnes of toxic sulfuric acid (H₂SO₄) and permanganate (KMnO₄) wastewater per kilogram of yield.
- •Permanent Lattice Damage: Harsh acid oxidation breaks basal planes, causing irreversible structural defects (ID/IG > 0.8) even after reduction.
- •Multi-Day Production Cycles: Requires slow oxidation, hazardous exothermic dilution, and exhaustive repetitive water washing.
- •Batch Inconsistency: High batch-to-batch variation driven by exothermic heat spikes and variable oxidation degrees.
Direct Conversion, Zero Liquid Effluent
- •Zero Liquid Effluent: 100% dry thermodynamic conversion with closed-loop heat recovery and zero toxic chemical runoff.
- •Intact sp² Carbon Lattice: Direct synthesis preserves pristine conjugated carbon bonds, yielding low defect density (ID/IG < 0.1).
- •Rapid Cartridge Turnover: Modular reusable cartridges enable fast reloading and continuous batch synthesis at industrial scale.
- •Automated In-line QA: Real-time laser Raman and XRD monitoring calibrate every production batch against certified COA standards.

Empirical Quality Verification
Characterization standards per batch.
In nanotechnology, quality claims require empirical verification. Every production cycle is cataloged against international structural standards (ISO/TS 21356-1) using three automated quality gates.
Laser Raman Spectroscopy
Raman is the gold-standard fingerprint for carbon materials. We measure the defect ratio (ID/IG peak intensity at ~1350 cm⁻¹ vs ~1580 cm⁻¹) and the symmetric 2D peak (~2700 cm⁻¹) to verify 2–5 layer thickness and intact sp² carbon bonding.
X-Ray Diffraction (XRD)
XRD proves successful exfoliation and crystalline order. Few-Layer Graphene demonstrates a broad, low-intensity (002) reflection, while our functionalized Graphene Oxide displays a characteristic d₀₀₂ shift to 0.75–0.85 nm confirming functional group insertion.
Particle Size Analysis (PSA)
Laser diffraction and dynamic light scattering analyze the lateral sheet distribution. We maintain a tight D50 envelope to guarantee consistent matrix coupling, predictable percolation thresholds, and rapid dispersion in resins.
Handling & Processing
Dispersion & integration protocols.
Optimal property translation from 2D sheets into polymer matrices or liquid coatings requires proper de-agglomeration and interfacial wetting.
FLG powder disperses optimally in polar aprotic solvents (NMP, DMF) and alcohols (IPA). Graphene Oxide is directly dispersible in deionized water without surfactants.
High-shear mixing (3,000 – 6,000 RPM) or planetary centrifugal mixers provide sufficient shear energy to break Van der Waals agglomerates without fracturing lateral flake dimensions.
For epoxy and polyurethane systems, pre-mix graphene with the resin component before adding the curing agent to ensure uniform distribution and avoid resin localized pre-cure.
Store powders in sealed, airtight containers at ambient room temperature (18–25°C) in dry conditions. Avoid prolonged ambient exposure to prevent moisture absorption.
Reliability & Supply Assurance
Production consistency & order fulfillment.
How do you assure enterprise clients of batch-to-batch consistency?
Every shipment is issued with a certified Certificate of Analysis (COA) cross-referenced to its reactor batch ID. Quality is verified using laser Raman spectroscopy (ID/IG defect ratio), X-ray diffraction (XRD crystalline order), and particle sizing (D50) before packaging.
Can Velcoris customize flake size (D50) and surface chemistry?
Yes. Our synthesis platform allows tuning of lateral flake distribution (D50 from 5 µm to 20 µm) and tailored functionalization levels (Few-Layer Graphene vs Graphene Oxide) to match specific viscosity and bonding requirements in your resin, coating, or battery slurry.
What is the minimum order quantity (MOQ) for industrial clients?
We fulfill custom volume requirements ranging from small R&D evaluation kits (100g – 1kg) for lab validation up to industrial multi-kilogram and tonnage batch deliveries for commercial production runs.
Is the Velcoris manufacturing process compliant with environmental regulations?
Yes. Unlike legacy chemical exfoliation (Modified Hummer’s Method) which consumes hundreds of liters of water and concentrated acids per kilogram, our closed-loop thermodynamic reactor produces zero liquid effluent and incorporates heat recovery systems.
