セラミックス坏土、セラミックス成形体、セラミックス構造体及びこれらの製造方法
Document Type and Number:
Japanese Patent JP5560081
Kind Code:
B2
Abstract:
An object of the invention is to reduce, in a ceramic clay containing a layered double hydroxide, the content thereof while keeping good moldability or formability, thereby reducing the cost of a ceramic structure manufactured using the ceramic clay and improving product properties. The ceramic clay is available by kneading a forming raw material containing a ceramic forming material. The forming raw material contains, in addition to the ceramic forming material, a layered double hydroxide represented by a predetermined chemical formula in an amount of from 0.01 to 5 mass% based on the total amount of them. The layered double hydroxide turns into a gel by dispersing it in water and when it is dispersed in water at a concentration of 6 mass%, it has a viscosity of from 1000 to 20000 mPa·s.
