SILICON NITRIDE WAVE-TRANSMITTING MATERIAL, PREPARATION PROCESS AND PREPARATION APPARATUS

WIPO Patent Application WO/2024/082697

A1

A silicon nitride wave-transparent material preparation apparatus, comprising a slurry tank (1); a sealing cover (2) arranged on the upper part of the slurry tank; a pulverizing cylinder (3) arranged above the slurry tank and communicated with the interior of the slurry tank by means of a through hole formed in the center of the sealing cover; a refining mechanism arranged in the pulverizing cylinder; and a blending assembly arranged in the slurry tank. Solid raw materials are refined in the pulverizing cylinder, and then can be directly put into the slurry tank containing liquid materials without intermediate transfer, preventing the refined powder material from being doped with other substances in the intermediate transfer process; in addition, the intermediate transfer procedure is eliminated, so that the preparation period is shortened.
