摘要： The present invention provides a method for manufacturing an oxide ceramic molded body that enables high-yield production of a molded body in a convenient fashion using a powder of oxide ceramic particles having a nano-sized average primary particle diameter (particularly, 120 nm or less). The present invention relates to a method for manufacturing an oxide ceramic molded body, comprising subjecting a powder containing oxide ceramic particles with an average primary particle diameter of 1 to 120 nm to press molding under reduced pressure. Preferably, the press molding is conducted under a reduced pressure of 0.1 to 100 kPa.
