Embodiment 1)
[0144] Put 100g of barium titanate (average particle diameter calculated from BET specific surface area: 50nm) and 4.0g of dispersant B6 (active ingredient) into a 500mL container together with 500g of zirconia beads with a diameter of 1mm, add toluene / ethanol= A mixed solvent of 48 / 52 (volume ratio) was adjusted so that the solid content concentration of barium titanate was 50% by weight, and dispersion treatment was performed for 96 hours using a table-top bead mill.
[0145] Next, 14.0 g of polyvinyl butyral resin, 2.80 g of dioctyl phthalate, 1.0 g of cationic compound A1, and a mixed solvent of toluene / ethanol=48 / 52 (volume ratio) were added to the above dispersion treatment liquid, The solid content concentration of the barium titanate was adjusted to be 35% by weight, and the mixture was mixed for 2 hours with a benchtop bead mill, and then the zirconia beads were removed by filtration to obtain a ceramic slurry.
[0146] Next, the ceramic slurry was molded into a sheet...
Embodiment 2)
[0149] A ceramic green sheet was produced in the same manner as in Example 1 except that the cationic compound A2 was used instead of the cationic compound A1 in Example 1, and a multilayer ceramic capacitor was produced using the ceramic green sheet.
Embodiment 3)
[0151] A ceramic green sheet was produced in the same manner as in Example 1 except that the cationic compound A3 was used instead of the cationic compound A1 in Example 1, and a multilayer ceramic capacitor was produced using the ceramic green sheet.
