Title:

BATCH PROCESSING METHOD FOR SILICON NITRIDE CERAMIC MICROBEADS

Document Type and Number:

WIPO Patent Application WO/2022/041360

Kind Code:

A1

Abstract:

A batch processing method for a silicon nitride ceramic microbead, comprising the following steps: step 1, rough grinding: loading silicon nitride blank beads into a groove between an upper grinding plate and a lower grinding plate, adding a grinding medium for processing, and performing repeated cyclic grinding between the upper grinding plate and the lower grinding plate; step 2, fine grinding: adjusting the pressure and rotation speed between the upper grinding plate and the lower grinding plate, loading the silicon nitride ceramic microbeads obtained in step 1 between the upper grinding plate and the lower grinding plate, and adding a grinding medium for processing and grinding; step 3, fine grinding: selecting silicon nitride ceramic microbeads having no obvious processing defects on the surface from the silicon nitride ceramic microbeads obtained in step 2 for processing and grinding; step 4, fine grinding; and step 5, super fine grinding. Said processing method has a high efficiency, a reasonable design and low costs, is easy to operate, and has a high processing efficiency.
