Products   >   Aluminum nitride Large Particle Filler powder

Aluminum nitride large particle filler powder is produced by self developed aluminum nitride powder.After spraying,granulation and sintering,it is screened and packed. The products are widely used in TIM(thermal interface material).

Crushing: mechanical equipment is used for crushing,which greatly reduces the agglomeration of powder in microscopic observation,and reduces the sense of particle and roughness in tactility;
Particle size detection:particle size detection shall be carried out for filler powder after crushing and classification,and the particle size is no longer controlled only by sieve mesh The particle distribution of the improved classification is narrower than that before;
Products with different particle sizes can be customized according to customer requirements
