Key Points

The study aims to develop technology for recycling waste multilayer ceramic capacitors (MLCC) by utilizing a thermal treatment process.
Pre-crushed MLCC were subjected to thermal treatment at 1000°C in an ammonia and air atmosphere.
The powdered MLCC were processed to approximately 100 μm before heat treatment.
Sintered ceramic bodies were evaluated for their microstructure and dielectric properties.
MLCC were pulverized into approximately 1 μm ameboid particles during the treatment.
Nickel from the internal electrodes reacted, leading to the presence of nickel oxide in the recycled sintered body.
The relative density of the recycled ceramics was 71%, showing insufficient densification yet demonstrating a dielectric constant exceeding 1000.

Demonstrates effective recycling of ceramic capacitors, suggesting a promising method for waste reduction.
