MLCC (Multilayer Ceramic Capacitor), also known as chip capacitors, accounts for approximately one-third of the passive component market, with a global market size exceeding tens of billions of dollars.
Due to its characteristics such as high voltage resistance, compact size, long service life, and wide capacitance range, MLCC is widely used in consumer electronics, industrial applications, communications, automotive, and military sectors, earning the name “rice of the electronics industry.”

In the production process of MLCC, ceramic slurry is used during preparation and coating stages, while metal slurry is used in the printing process.
Ceramic slurry is applied for dielectric layers, while metal slurry is used for internal and external electrode formation.

The miniaturization of ceramic slurry particles provides benefits such as increased capacitance, reduced sintering temperature, and lower losses.
Similarly, the miniaturization of metal slurry particles enhances conductivity, reduces internal resistance, and supports high-frequency applications.

However, nanoscale particles are more prone to aggregation due to van der Waals forces, surface energy, and electrostatic interactions. This aggregation can lead to defects such as voids in dielectric layers, electrode impurities, and device cracking, which significantly affect product yield and performance.

How can slurry aggregation in MLCC processes be addressed?
There are generally two main approaches:

The first method involves the use of dispersants, which help disperse aggregated particles through electrostatic repulsion, steric hindrance, or a combination of both. However, due to continuous system dynamics, particles may re-aggregate over time.

The second method involves filtration, which removes aggregated particles and stabilizes the slurry system, ensuring consistent process quality.
