Study on Factors Influencing Interlayer of ITO Green Body by Pressure Slip Casting

ITO green body was prepared by pressure slip casting from solid high content slurry with ITO powder as the raw material. The effects of pore-size of mould, grain-size of powder and aid-filtration reagent green body were studied. The result showed that increasing the pore-size and adding aid-filtration reagent properly could decrease or even eliminate interlayer in the green body, meanwhile, interlayer-defects in the target material could be alleviated apparently with ITO powder of high sintering activity.
