Do any friends know what polishing solution is used in the finishing process of silicon carbide SiC?

The fine grinding process of silicon carbide (SiC) usually requires the use of a specific type of polishing solution in order to obtain the required surface quality during grinding and polishing. The choice of polishing solution usually depends on the process requirements and the required surface characteristics. The following are some types of polishing solutions that can be used in the SiC polishing process:

1. silicon carbide grinding fluid: This fluid is specially designed for SiC materials, and has proper viscosity and particle distribution, so as to effectively remove materials during grinding and obtain the required flatness of the surface. This grinding fluid usually contains silicon carbide particles, which is helpful to quickly grind SiC materials.

2. Alumina grinding fluid: Alumina grinding fluid can also be used for grinding and polishing SiC. This liquid contains alumina particles, which can be used to remove substances on the surface of SiC and improve the surface quality.

3. Polyurethane polishing solution: This kind of polishing solution is usually used in polishing process to further improve the flatness and quality of SiC surface. Polyurethane polishing solution is usually used in the final polishing step to obtain the required surface finish.

4. Silicon silicon carbide grinding fluid: In some high-precision applications, silicon silicon carbide grinding fluid may also be used. This liquid usually contains fine silicon carbide particles, which can be used for ultra-fine grinding and polishing.

The selection of polishing solution should be based on the specific SiC grinding and polishing process, required surface quality and equipment requirements. In practical application, it is usually necessary to determine the most suitable type of polishing solution according to the specific process and requirements.
