Title:
DISPERSION APPARATUS, PROCESS FOR PRODUCING CERAMIC SLURRY, LAMINATED CERAMIC ELECTRONIC COMPONENT AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/098091
Kind Code:
A1
Abstract:
A dispersion apparatus that with energy less than conventionally consumed, can efficiently disperse agglomerated particles in a slurry; a process for producing a ceramic slurry in which ceramic particles are dispersed by means of the dispersion apparatus; a laminated ceramic electronic component of high reliability produced using a ceramic green sheet formed from the ceramic slurry; and a process for producing the same. Extension stress is generated by causing a jet of slurry containing agglomerated particles to pass through dispersion part (3), and simultaneously the extension stress is applied to the agglomerated particles of the slurry to thereby attain dispersion of the agglomerated particles. The dispersion part (3) is so constructed that nozzle (10), first channel (11) for passage of the jet from the nozzle and tubular second channel (12) for passage of the jet having passed the first channel leading to generation of extension stress are arranged in sequence from the upstream side toward the downstream side.
