Why Is 90 Silicon Carbide Used for Surface Treatment

90 silicon carbide is widely used for surface treatment because of its high purity, strong cutting ability, and consistent abrasive performance. Compared with lower grades, 90 silicon carbide provides sharper grains and more stable results, making it suitable for applications such as grinding, polishing, and sandblasting where surface quality and precision are important.

The reason 90 silicon carbide is used for surface treatment lies in its material properties.

With higher purity, 90 silicon carbide contains fewer impurities that could affect performance. Its grains are sharper and more uniform, which allows it to remove material efficiently while maintaining better control over the surface.

In practical applications, this means:

• faster cutting action
• more consistent surface finish
• reduced variation during processing

In surface treatment processes, consistency is often more important than speed.

90 silicon carbide is used because it produces a more uniform abrasive action. The higher purity reduces irregular particles, which can otherwise cause scratches or uneven finishes.

Production result:

• smoother and more controlled surface finish
• fewer defects or irregular marks
• improved final product quality

Both 88 and 90 grades are used in industry, but their roles are different.

• 88 silicon carbide → more cost-effective, suitable for general applications
• 90 silicon carbide → higher purity, better for precision and surface quality

When surface requirements are stricter, 90 silicon carbide is used for surface treatment because it provides:

• stronger cutting precision
• more stable performance
• better repeatability

Due to its performance, 90 silicon carbide is used in:

• sandblasting and surface cleaning
• grinding and polishing of hard materials
• glass and ceramic surface processing
• metal surface preparation before coating

These applications require both cutting ability and surface control, which 90 silicon carbide can provide.

Although higher purity materials may cost more, 90 silicon carbide is used because it improves overall efficiency.

Its sharper grains reduce the time needed for material removal, and its consistency reduces the need for rework.

Production result:

• shorter processing time
• fewer defects
• reduced material waste

90 silicon carbide is preferred when:

• high surface quality is required
• material is hard or brittle (glass, ceramics)
• consistent results are critical
• surface defects must be minimized

In these cases, 90 silicon carbide is used for surface treatment to achieve better control and precision.

In one sandblasting process, lower-grade abrasive material was used, resulting in uneven surface quality and visible scratches.

After switching to 90 silicon carbide, the process became more stable.

Result:

• surface finish became more uniform
• fewer defects appeared
• rework was reduced

This example shows why 90 silicon carbide is widely used for surface treatment when quality requirements are higher.
