Silicon carbide plate production process

1. Raw material preparation

Raw material selection：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.

Mixing: 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. sintering

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-processing

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.

Transportation: Ensure that damage is avoided during transportation, especially in long-distance and cross-border transportation.
