Description

Technical Field

[0001] The utility model relates to the technical field of silicon nitride production, in particular to a silicon nitride collection platform. Background Technique

[0002] Silicon nitride is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material with high hardness, lubricity, wear resistance, and is an atomic crystal; it has oxidation resistance at high temperatures. Moreover, it can resist thermal shock. When heated above 1000°C in air, cooled rapidly and then heated rapidly again, it will not break. Due to the excellent properties of silicon nitride ceramics, people often use it to manufacture mechanical components such as bearings, turbine blades, mechanical seal rings, and permanent molds.

[0003] In the production process of silicon nitride, it first needs to be extruded into a plate-like structure through a mold, and then formed into a plate by sintering. In this process, after extrusion molding, a large amount of granular silicon nitride raw materials will remain on its surface, which will cause the silicon nitride raw materials to fall off during its transportation, affecting the forming station and causing waste of raw materials.
