SILICON NITRIDE AUTOGENOUS GRINDING.

摘要

The present invention discloses a process for silicon nitride grinding, the silicon nitride being in a liquid suspension. The process is characterized in that grinding is performed in an autogenous manner, and in that said silicon nitride comprises at least 30 percent by weight in said suspension; the advantages of said process are essentially characterized in that the performance thereof is easier and cheaper, and in that the quality of the ground silicon nitride is improved.
