Nickel Slag Abrasive, Fayalite-Based Abrasive, Ferronickel Slag, Industrial Nickel Slag Abrasive Grit, 69012-29-9

INDUSTRIAL NICKEL SLAG ABRASIVE GRIT

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

Short Identity Section

Detailed Identification

Explanation:
Nickel Slag Abrasive (Fayalite Structure) is an amorphous, glassy, high-density synthetic mineral obtained by controlled water/air quenching of molten slag generated during nickel metallurgical smelting processes, followed by mechanical crushing and screening. Its ultra-sharp angular grain morphology and high hardness of 6.5 – 7.0 Mohs make it an aggressive abrasive that provides maximum speed and penetration, especially on heavily corroded metal surfaces, thick coating layers, and large open-area blasting operations. According to ECHA, it is registered as “Slags, ferronickel-manufg.” with EC number 273-729-7.

2. PHYSICAL AND CHEMICAL PROPERTIES

Note: The pH value is approximately 9–11 due to the alkaline nature of the slag. Values are typical and may vary according to production source and batch.

3. SOLUBILITY PROFILE

Note: Insoluble in water due to its chemically inert structure. Data for organic solvents are not available.

4. CHEMICAL PROPERTIES AND REACTIONS

Chemical and Mineralogical Composition

Note: Elements are not present as free metals but as stable oxide bonds. Values are typical and may vary according to production source and batch.

5. SPECIFICATIONS

Particle Size and Application Selection Table

Note: Due to its high-density structure, particle momentum is high. Fractions are selected according to the target Sa surface cleanliness grades.

6. APPLICATIONS AND INDUSTRIAL USES

6.1 Process and Performance Advantages

• High Aggressive Cutting Power: Thanks to its sharp angular geometry and high Mohs hardness, it rapidly cuts and removes surface layers rather than scraping them. It reduces labor and time costs by up to 30%.

• High Kinetic Energy (High Density): Since it has a higher specific gravity compared to other mineral abrasives, the impact force combined with nozzle exit velocity is much higher. It easily blasts off thick scale and mill scale.

• Zero Free Silica Risk: Since the crystalline free silica content is below 0.1%, it does not cause silicosis risk in open-area blasting operations. It fully meets occupational safety standards.

• Single-Use System Economy: It offers high consumption efficiency and optimum cost, especially in open-area, bridge, dam, and shipyard blasting projects where recovery is impossible or costly.

6.2 Application Methodology and Equipment Criteria

• Equipment Type: Designed for use in pressurized air blast pot blasting machines and open-area blasting systems.

• Working Pressure: To maximize the cutting power of the material, the ideal working pressure should be 6.5 – 8.5 bar behind the nozzle.

• Nozzle Durability: Considering the high abrasiveness of the material, Boron Carbide (B₄C) venturi type nozzles should definitely be preferred to minimize nozzle wear.

7. BIOLOGICAL AND STRUCTURAL PROPERTIES

Note: This product is an industrial abrasive mineral. It is not intended for biological, pharmaceutical, or food applications.

8. BIOCHEMICAL APPLICATIONS

Note: Not applicable for this industrial abrasive product.

9. SAFETY AND TOXICOLOGY

Health, Safety & Environment (from source TDS):

• Zero free silica risk; crystalline free silica content is below 0.1%.

• Does not cause silicosis risk in open-area blasting operations.

• Fully meets occupational safety standards.

• Chemically inert and stable structure.

• Use appropriate PPE during blasting operations.

• Follow local occupational health and safety regulations.

Critical Toxicological Warning: Because nickel slag contains nickel compounds, it carries a risk of skin sensitization and carcinogenicity. Prolonged exposure through dust inhalation may cause lung damage. Therefore, the use of appropriate respiratory protection (P2/P3 mask) during blasting operations is mandatory.

10. TRANSPORT INFORMATION

Note: Transport classification is UN 3077 due to nickel slag being classified as an environmentally hazardous substance. Verify with supplier SDS before shipment.

11. REGULATORY INFORMATION

Note: This product is an industrial abrasive and is not intended for pharmaceutical or food applications.

12. STORAGE AND HANDLING

13. FIREFIGHTING MEASURES

Note: Nickel slag is non-combustible but may pose a metal fire risk in powder form. Avoid using water during firefighting.

14. ACCIDENTAL RELEASE MEASURES

Note: The source TDS does not contain a specific accidental release section. The above are general safe practices consistent with the product’s HSE information.

15. FIRST AID MEASURES

Note: In case of exposure to nickel compounds, if skin sensitization (allergic reaction) has developed, medical attention is recommended.

20. SUMMARY AND CRITICAL WARNINGS

SUMMARY

Nickel Slag Abrasive (Fayalite Structure) is an amorphous, glassy, high-density synthetic mineral obtained by controlled water/air quenching of molten slag generated during nickel metallurgical smelting processes, followed by mechanical crushing and screening. Its ultra-sharp angular grain morphology and high hardness of 6.5 – 7.0 Mohs make it an aggressive abrasive that provides maximum speed and penetration, especially on heavily corroded metal surfaces, thick coating layers, and large open-area blasting operations.

It appears as bright black, dark fume, or glassy. Its hardness is 6.5–7.0 Mohs, true density is 3.20–3.60 g/cm³, and apparent bulk density is 1.70–1.95 g/cm³. Moisture content is ≤0.1%, water-soluble chlorides are ≤0.0015% (15 ppm), and conductivity is ≤15 mN/m (150 μS/cm). Free crystalline silica is below 0.1% (undetectable level).

It is used for removal of thick tar, epoxy, antifouling paint layers on ship hulls; deep corrosion cleaning in heavy industry, shipyards, and bridge projects; internal/external surface cleaning of oil tanks, silos, pipelines; pre-paint roughening of structural steels; cleaning of new production sheets, light rust removal, casting deflashing, and sensitive metal surface preparation.
