Silicon carbide plate production process
1. Préparation des matières premières
- Sélection des matières premières：High-purity silicon powder and carbon powder (such as graphite) are the main raw materials and usually need to be processed to micron-level particle size.
- Mélange: Mix silicon powder and carbon powder in a specific ratio to ensure uniform composition.
2. forming
- Dry pressing: The mixed powder is pressed into shape using cold isostatic pressing (CIP) or dry pressing.
- Injection molding: used for products with complex shapes, the powder is mixed with a binder and then injected into a mold for molding.
3. frittage
- Pressureless Sintering：Sintering is carried out in a high temperature furnace without external pressure, which is suitable for large-scale production.
- Hot Pressing：Sintering under high temperature and high pressure can improve product density and mechanical strength.
- Reaction Bonding：Silicon reacts with carbon to form SiC, while filling the pores and increasing the density of the material.
4. Post-traitement
- Machining: Through cutting, grinding and polishing, the product can reach the required size and surface finish.
- Coating: According to the application requirements, anti-oxidation or wear-resistant coating can be added to the surface.
5. Quality Inspection
- Density measurement: Detects the density of the material.
- Hardness test: Evaluates the wear resistance and mechanical strength of the material.
- Microstructure analysis: Analyzes the grain structure and microscopic defects using an electron microscope.
6. Packaging and Shipping
- Packaging: Appropriate packaging is carried out according to product characteristics and transportation requirements.
- Transport: Ensure that damage is avoided during transportation, especially in long-distance and cross-border transportation.
