Embodiment

[0097] Hereinafter, the present invention will be described in more detail with reference to Examples. However, the present invention is not limited to the following examples.

[0098](1) Preparation of firing slurry composition [Examples 1 to 34 and Comparative Examples 1 to 10]

[0099] The components shown in column A (column corresponding to "inorganic powder", "solvent", "dispersant" and "aminoalcohol compound") in Tables 1 to 4 were put into a ball mill to obtain a mixture, and stirred with a ball mill 30 minutes to disperse the mixture. Subsequently, the components in column B (corresponding to the column of "defoamer and polyvinyl alcohol resin") in Table 1 to Table 4 were further added, and stirred in a ball mill for 8 hours to disperse, thereby preparing a fired slurry combination.

[0100] Details of the components shown in Tables 1 to 4 are shown below.

[0101] [Inorganic Powder]

[0102] iron oxide

[0103] [Dispersant]

[0104] Polyacrylate ammonium salt ...

Abstract

The present invention addresses the problem of providing a slurry composition for firing, from which it is possible to form a sheet that exhibits high flexibility while maintaining high sheet strength. This slurry composition for firing contains an amino alcohol compound (A) represented by a formula (1), an inorganic powder (B), a poly(vinyl alcohol) resin (C) and water. In the formula (1), R is ahydrogen atom or an alkyl group having 1-20 carbon atoms. m and n are numbers that satisfy the inequalities m>=0, n>=0 and m+n>=1.

Description

technical field [0001] The present invention relates to a firing slurry composition, a green sheet, a method for manufacturing a green sheet, a method for manufacturing a sintered product, and a method for manufacturing a monolithic ceramic capacitor. More specifically, the present invention relates to a fired slurry composition for producing a sintered product of an inorganic powder, a green sheet comprising a dried product of the fired slurry composition, a method for producing a green sheet, a method for producing a sintered product Methods and methods for making monolithic ceramic capacitors. Background technique [0002] Conventionally, an organic solvent such as typically toluene has been blended as a solvent with a firing binder composition, a firing slurry composition, etc. to produce ceramic green sheets. [0003] In recent years, along with concerns about the effects of volatile organic compounds (VOCs) and the like on the environment and human body, regulations o...
