The present invention discloses crystallized silicate-synthetic powder comprising a cordierite (2MgO.2Al2O3.5SiO2) crystalline phase, a mullite (3Al2O3.2SiO2) crystalline phase and a corundum (Al2O3) crystalline phase, and discloses a high-heat resistant porcelain body containing the above crystallized silicate-synthetic powder and formed by mixing the crystallized silicate-synthetic powder and kaolin mineral.
摘要:
A method of reducing the defects in ceramic articles and precursors, particularly ceramic articles and precursors made using a batch composition containing an oil phase material. The method includes increasing the concentration of a water insoluble soap in the batch composition, which can increase the cohesive strength of the oil phase, leading to a reduction in the incidence of defects in the ceramic articles and precursors.
摘要:
The ceramic clay is provided 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 the layered double hydroxide and the ceramic forming material. The layered double hydroxide turns into a gel when dispersed in water, and when the layered double hydroxide is dispersed in water at a concentration of 6 mass %, the layered double hydroxide has a viscosity of from 1000 to 20000 mPa·s.

摘要:
A ceramic particle group dispersed in a solvent in a state of primary particles of single crystal, a method for production thereof and a use thereof are disclosed. In one embodiment a method is disclosed for producing a sintered particle (ceramic particle) group of hydroxyapatite (HAp), which includes a step of subjecting a system wherein calcium carbonate is present between primary particles of hydroxyapatite (HAp) to sintering and then dissolving calcium carbonate with water to remove calcium carbonate. A hydroxyapatite (HAp) sintered particle group produced by the above method is a nanometer size particle group having a particle diameter of about 70 to about 120 nm, and is a particle group having a uniform particle diameter (coefficient of variation: 12%), and further 96% of the particle group is dispersed as a single crystal particle.
