摘要： A method for controlling the shrinkage of ceramic formed bodies is provided, including performing a preliminary test to determine an average shrinkage of ceramic formed bodies made from test lots of a ceramic powder, and determining a linear correlation between the average shrinkage and measured amounts of the ground test lots removed from a ball mill during a specific milling time interval. A batch of the ceramic powder is then ground, an amount of the ground ceramic powder removed from the ball mill during the specific time interval is measured, and the linear correlation is used to estimate the shrinkage of a ceramic body made therefrom. The difference between a target shrinkage and the estimated shrinkage is determined, and one or more of the processing conditions used to form the ceramic body are changed to offset the difference.

摘要： The present invention provides a method for controlling the shrinkage of formed ceramic bodies, by which it is possible to suppress fluctuation of the shrinkage of formed ceramic bodies and to cause the shrinkage to approximate the target rate. The method comprises controlling the shrinkage of formed ceramic bodies in manufacturing ceramic products by a predetermined manufacturing process from ceramic powder ground by a dry-type ball mill. Such control can be achieved by determining a correlation between the change in the amount of the ground ceramic powder taken out from the dry-type ball mill with elapse time and the shrinkage during firing of the formed ceramic body, and thereafter adjusting the manufacturing conditions based on the previously-determined conditions for the above-mentioned manufacturing process and the correlation with respect to the shrinkage obtained.
