Silicon Nitride

Silicon nitride powder is a very hard ceramic powder that is used for both abrasion resistance and as an insulator for electronics. Depending on the size of the powder, sieving silicon nitride can be an easy or very difficult process. To classify silicon nitride when it is a coarser powder, the user needs to closely monitor the level on the screen. The powder is extremely abrasive and must be sieved gently or it will quickly rip the screen mesh. Sieving silicon nitride at finer sizes is usually not as difficult and can be done easily on the right piece of equipment.

Contract Manufacturing Experience

Sieving silicon nitride powder needs to be done carefully to avoid tearing the screen mesh. For coarser grades of silicon nitride, using a Minox Tumbler Screener, Elcan can finesse particles through the sieve mesh using the gyratory motion. This will allow for a precise classification while drastically decreasing the likelihood of ripping the screen mesh. For sieving silicon nitride at finer sizes, the high energy of the hi-sifter system can handle this without issue down to 15 microns.
