**Product Overview**
Spherical alumina is produced through high-temperature flame melting and advanced processing techniques. This material undergoes precise classification and recycling during production to ensure uniform particle size and excellent thermal performance. It is widely used in electronics, heat dissipation systems, and industrial applications due to its high fluidity, stability, and oxidation resistance.
**Key Features**
1. **High Purity & Uniformity**: Spherical shape ensures even distribution, consistent quality, and excellent surface properties.
2. **Superior Thermal Conductivity**: Ideal for heat dissipation with stable thermal expansion coefficients (e.g., L10/12 standards).
3. **Excellent Flowability**: Smooth surface and optimized particle size enhance processing efficiency.
4. **Strong Durability**: High hardness, wear resistance, and chemical stability for demanding environments.
5. **Customizable Viscosity**: Available in low, medium, and high viscosity options to suit various applications.
**Applications**
- **Electronics**: Heat sinks for CVD devices, polymer components, power adapters, transformers, and outdoor electrical equipment.
- **Industrial Materials**: Thermal interface materials, coatings, and flame-retardant/explosion-proof products.
- **Advanced Manufacturing**: Used in CVD reactors, electroplating systems, and high-temperature processing equipment.
