METHOD FOR CALCINING CERAMIC

PURPOSE:To shorten a calcination time, while preventing the generation of cracks and blisters. CONSTITUTION:The concentration of oxygen is held at 12-15% in an oven in a temperature region of 700-1000 deg.C and in a holding temperature region of approximately 1000 deg.C. Namely, the oxygen concentra...

Summary:PURPOSE:To shorten a calcination time, while preventing the generation of cracks and blisters. CONSTITUTION:The concentration of oxygen is held at 12-15% in an oven in a temperature region of 700-1000 deg.C and in a holding temperature region of approximately 1000 deg.C. Namely, the oxygen concentration of the atmosphere is enhanced in a process ranging from a temperature region for releasing the crystal water of clay components to a temperature region for transferring a calcination article from a porous state into a dense state. Thereby, organic substances contained in the article are burnt off in a good state in a short time without generating blisters.
