Hexaferrite Ceramic Magnet Technology: Advantages & Applications
Hexaferrite (SrFe12O19 / BaFe12O19) ceramic magnet production technology — materials, sintering methods, property optimization, and industrial applications. Khat Group developed Iran's first domestic hexaferrite production line, eliminating multi-million dollar annual imports.
Hexaferrite ceramic magnets (SrFe₁₂O₁₉ / BaFe₁₂O₁₉) combine high thermal stability, mechanical strength, chemical resistance, and corrosion resistance — making them ideal substitutes for steel and alloys in many industrial applications. Khat Group developed Iran’s first domestic hexaferrite production line, eliminating multi-million dollar annual imports.
Hexaferrite Production Technology
Raw Materials
High-purity ceramic powders, nano-additives, and binders — raw material quality directly determines magnetic properties.
Production Process
- Milling & mixing — Controlled particle size distribution
- Compaction & shaping — Dry/wet pressing with/without magnetic field
- Sintering — Conventional, spark plasma (SPS), hot pressing, or CIP
- Property optimization — Microstructure control, grain boundary engineering
Sintering Methods
| Method | Advantage |
|---|---|
| Conventional | Cost-effective, scalable |
| Spark Plasma Sintering (SPS) | Rapid, fine microstructure |
| Hot Pressing | High density, anisotropic properties |
| Cold Isostatic Pressing (CIP) | Uniform density, complex shapes |
Key Advantages of Hexaferrite Magnets
- High temperature stability — Operate up to 450°C
- High mechanical strength — Hard, brittle but strong
- Chemical inertness — Resistant to acids, bases, oxidation
- Corrosion resistance — No coating needed in most environments
- Cost-effective — Lower cost than rare-earth magnets
Applications
- Motors & generators — Small motors, separators, speakers
- Automotive — ABS sensors, wiper motors, fuel pumps
- Electronics — Transformers, inductors, EMI suppression
- Home appliances — Refrigerator seals, microwave components
- Industrial — Magnetic separators, holding devices, sensors
Khat Group Achievement
Khat Group, in partnership with a private company, achieved Iran’s first domestic hexaferrite production know-how after 6 months of intensive R&D with universities and research centers. The line meets international standards (ASTM-C1, IEC S1-0-1/2, MMPA 1.0/3.3, Chinese Y10T/Y8T) and eliminates annual multi-million dollar imports.
