Verifying authenticity protects your investment from fraud. This guide covers testing methods and verification procedures.
Common Gallium Fraud Schemes
Scam 1: Misidentified Metal
How It Works
- Similar-looking metal substituted
- Aluminum, zinc, or tin claimed as gallium
- Surface treatment to mimic gallium
- Certificate provided fraudulently
Metal Similarities
- Aluminum: Similar color, much lighter
- Zinc: Similar color, different density
- Tin: Similar appearance, wrong density
- Visual inspection alone insufficient
Detection Method
- Weight/density measurement
- Theoretical gallium density: 5.903 g/cm³
- Calculate actual density
- Comparison reveals substitution
Scam 2: Lower Purity Misrepresented
How It Works
- Lower purity (3N) sold as higher (5N)
- Testing certificate fabricated
- Visual inspection insufficient
- Laboratory testing avoided
Price Impact
- 3N cost: $40-60/gram
- 5N cost: $120-200/gram
- Fraud profit: 100-400%
- Significant financial incentive
Detection Method
- Independent laboratory testing
- ICP analysis for purity
- Compare results to documentation
- Request original lab confirmation
Scam 3: Counterfeit Certificates
How It Works
- Fake Certificate of Analysis created
- Fraudulent lab signature
- False lab contact information
- Appears professional
Red Flags
- Lab information easily checked
- Contact number doesn't work
- Lab denies issuing certificate
- Document has obvious errors
- Unusual certificate format
Verification
- Call laboratory directly
- Request confirmation
- Ask for certificate number
- Verify issuer details
- Check for document tampering
Scam 4: Mixed Grade Deception
How It Works
- Quantity of high purity listed
- Actual mixture of purities
- Only surface tested
- Lower purity hidden inside
Detection Method
- Request random sampling
- Test multiple sections
- Verify homogeneity
- Request batch consistency guarantee
Scam 5: Form Substitution
How It Works
- Powder sold as ingot
- Powder-compressed form used
- Different properties misrepresented
- Form value differs from claimed
Detection
- Physical inspection required
- Weight consistency check
- Professional examination
- Structural analysis if needed
Visual Inspection Techniques
Color & Appearance Assessment
High-Purity Gallium Characteristics
- Bright silver color
- Metallic luster
- Reflective surface
- Minimal oxidation
- Clean appearance
Suspicious Characteristics
- Dull appearance
- Non-metallic finish
- Heavy oxidation
- Discoloration
- Coating or paint
Limitations
- Visual inspection insufficient alone
- Must combine with other methods
- Expert eye helpful
- Not definitive proof
Surface Condition Analysis
Quality Indicators
- Smooth, uniform surface
- No pitting or corrosion
- Intact protective coating
- Professional appearance
- Proper packaging
Warning Signs
- Rough or rough texture
- Deep corrosion marks
- Protective coating damage
- Sloppy appearance
- Poor packaging
Form Verification
Ingot Authenticity
- Check dimensions
- Verify weight (within 0.5%)
- Examine edges and corners
- Assess overall integrity
- Compare to reference images
Wafer Authenticity
- Check thickness consistency
- Verify diameter
- Assess polishing quality
- Check for defects
- Examine edge quality
Density Measurement Method
Precise Density Calculation
Required Equipment
- Precision scale (±0.01g accuracy)
- Precise measuring device
- Ruler or calipers
- Calculator
Step-by-Step Process
-
Measure Dimensions
- For ingot: length, width, height (in cm)
- For cylinder: diameter and length
- For irregular: water displacement
- Record all measurements
-
Calculate Volume
- Volume (cm³) = length × width × height
- For cylinder: π × (diameter/2)² × height
- For irregular: water displacement method
- Record calculation
-
Weigh Sample
- Zero scale with container
- Place sample carefully
- Record weight in grams
- Repeat measurement for verification
-
Calculate Density
- Density = Weight (g) / Volume (cm³)
- Gallium theoretical: 5.903 g/cm³
- Compare to theoretical
- Calculate percentage deviation
-
Interpret Results
- <0.1% deviation: Very pure (likely authentic)
- 0.1-0.5% deviation: Acceptable purity
-
0.5% deviation: Significant contamination (suspect)
-
2% deviation: Likely fraudulent
Example Calculation
Ingot Specifications
- Length: 5.0 cm
- Width: 2.0 cm
- Height: 1.5 cm
- Weight: 89.4 grams
Calculation
- Volume = 5.0 × 2.0 × 1.5 = 15 cm³
- Density = 89.4 / 15 = 5.96 g/cm³
- Theoretical = 5.903 g/cm³
- Deviation = (5.96 - 5.903) / 5.903 = 0.97%
- Interpretation: Slightly high (possible minor impurity)
Accuracy Sensitivity
- Weight error ±0.1g = ±0.1% density error
- Dimension error ±0.1cm = ±1-2% density error
- Combined precision critical
