METHODS OF PRODUCING CERAMIC MOLDED PRODUCT AND TRANSPARENT SINTERED BODY
A transparent sintered body having fewer air bubble-derived defects is provided. More specifically, a method is provided of producing a ceramic molded product including at least a step of pressure-molding ceramic granules having a Hausner ratio, which is a quotient obtained by dividing a tapped bulk density by a loose bulk density, of 1.0 or more but not more than 1.2. Also provided is a method of producing a transparent sintered body including at least each of the steps of the above method to obtain a ceramic molded product and a step of heating and sintering the resulting ceramic molded product. The transparent sintered body has a linear transmittance of 78% or more at a wavelength of 600 nm to 2000 nm inclusive except for an element-derived characteristic absorption wavelength.
