COMPOSITION FOR LOW-TEMPERATURE FIRING PORCELAIN AND METHOD FOR MANUFACTURING LOW-TEMPERATURE FIRING PORCELAIN

摘要

PROBLEM TO BE SOLVED: To provide a composition for low-temperature firing porcelain which can be fired at a low temperature of 1,100°C or lower and allowing the strength of the porcelain to be further increased, and to provide a method for manufacturing the low-temperature firing porcelain which makes further more mass production possible by permitting a wider firing temperature range.;SOLUTION: The composition for low-temperature firing porcelain includes A component comprising silica and a clay component, and B component comprising feldspar, bone ash and petalite. Therein, a content of the A component is 20 to 80 wt.% and a content of the B component is 80 to 20 wt.%. Further, the method for manufacturing the composition includes: a process of mixing the A component with the B component; a process of grinding the mixed respective components into an average particle size of 11 μm or less; and a firing process of kneading and forming the ground respective components and firing the formed body at a temperature of not lower than 1,030°C and lower than 1,100°C.;COPYRIGHT: (C)2011,JPO&INPIT
