Every SAT NANO product passes through our in-house Quality Control Center, where HPLC, GC, ICP-OES, laser particle size analysis and electron microscopy (SEM/TEM) are used to test each batch for particle size distribution, purity, elemental composition and microscopic morphology — so that the material you receive matches its declared specification.

SAT NANO is ISO 9001 certified and operates a complete quality management system spanning incoming inspection (IQC), in-process control (PQC), final quality control (FQC), comprehensive testing and pre-delivery verification. These gates keep production efficient, stable and under full process control, batch after batch.

SAT NANO Nanomaterial Manufacturing Process

Taking the production and control process of MAX, MAB, MXene and other products as an example.

Stage 1: Raw Material Pre-treatment & High-Temperature Synthesis

Process & Technical Workflow:

1. High-Purity Precursor Formulations: Microcomputer-controlled precision weighing of high-purity elemental powders (e.g., Ti, V, Nb, Mo, Cr, Al, C, B) with milligram-level stoichiometric accuracy under an inert protective atmosphere.

2. Vacuum Inert Atmosphere Sintering: The homogeneous precursor mixture is processed in high-temperature vacuum tube/atmosphere furnaces under high-purity Argon (Ar) shielding. Programmed thermal profiles (1100°C–1600°C) drive complete solid-state phase transformation into multi-crystalline MAX/MAB phase precursors.

3. Phase Purity Verification: Rapid in-line XRD screening confirms 100% reaction completeness with zero unreacted elemental residues.

Stage 2: Precision Micro-Processing & Multi-Layer Chemical Exfoliation

Process & Technical Workflow:

1. Planetary Milling & Jet Pulverization: Multi-stage planetary ball milling and protective airflow jet pulverization reduce synthesized bulk precursors into uniform 200–400 mesh micro-powders.

2. Selective Chemical Etching: Micro-powders are transferred into temperature-controlled acid-resistant reactors at calibrated solid-to-liquid ratios. Tailored etchants selectively remove atomic 'A' layers (such as aluminum layers).

3. Multi-Stage Centrifugal Washing: Continuous high-speed refrigerated centrifugation washes the suspension to neutral pH, yielding high-purity multi-layer accordion-like 2D MXene/MAB nanostructures.

Stage 3: High-Pressure Microfluidization & Ultrasonic Nano-Dispersion

Process & Technical Workflow:

1. Industrial-Grade Ultrasonic Intercalation: High-power probe ultrasonic homogenizers equipped with constant-temperature circulating cooling break multi-layer stacks into few-layer and single-layer nanosheets.

2. High-Pressure Microfluidization: Operating at pressures up to 150–200 MPa, the microfluidizer achieves uniform sub-micron and nanoscale colloidal stabilization without shear damage.

3. Solvent Customization & Tyndall Effect Verification: Formulations are customizable in deionized water, NMP, ethanol, or organic matrices. Laser beam transmission verifies the pronounced, uniform Tyndall Effect, confirming exceptional colloidal stability.

Stage 4: Advanced Characterization & Comprehensive Quality Control

Process & Technical Workflow:

1.Microstructure & Morphology (FE-SEM / HR-TEM): Field Emission SEM verifies particle morphology, accordion layer spacing, and lateral nanosheet dimensions.

2.Crystal Phase & Structure Qualification (XRD): Full-spectrum X-ray diffraction maps characteristic peak shifts, confirming complete etching/exfoliation and phase purity。

3.Particle Size Distribution & Zeta Potential (DLS): Dynamic Light Scattering determines hydrodynamic particle size and surface charge), validating long-term dispersion stability.

4.Elemental Quantitative Analysis (ICP-OES / XRF): Measures trace elements and stoichiometric ratios to guarantee strict batch-to-batch consistency. Each shipment includes an official Certificate of Analysis (COA).

Stage 5: Cleanroom Precision Packaging & Vacuum-Sealed Delivery

Dual-Layer Protective Packaging:

1. Nanopowders: Packaged in anti-static multi-layer aluminum foil pouches, backfilled with high-purity Argon (Ar), and hermetically heat-sealed under high vacuum.

2. Colloidal Dispersions: Bottled in UV-blocking amber fluorinated containers with Teflon-lined leak-proof caps.
