다성분 용매와 암모늄계 분산제가 적용된 투명 유전체 프릿트 슬립의 분산거동 = Dispersion Behavior of Transparent Dielectric Glass Frits in the Multi-Solvent and Ammonium-Type Dispersant System

다국어 초록 (Multilingual Abstract)

Dispersion behavior of the slurries consisted of Pb or Bi-based glass frits, which are used for the fabrication of green sheet as PDP front panel transparent dielectric, was examined in non-aqueous solvent system. Measurements of sedimentation height and viscosity were conducted to determine proper dispersion condition in the various solvent and dispersant system. Azotropic compound and ethyl acetate were used as the solvent and ammonium-type dispersant was applied to the slurries. All slurries were dispersed well in azotropic solvent system involving 20$\sim$50 vol% ethyl acetate at 2$\sim$3 wt% dispersant content. Especially, dispersion behavior was notably improved in the addition of ethyl acetate in the Bi-based frit slurry.
