ABSTRACT:
A ceramic material powder for a translucent ceramic is molded with a binder, and the resulting green compact is embedded in a ceramic powder having the same composition with the ceramic material powder. After removing the binder, the green compact embedded in the ceramic powder is fired in an atmosphere having an oxygen concentration higher than that in the removal procedure of the binder and thereby yields a translucent ceramic represented by Formula I: Ba{(SnuZr1-u)xMgyTaz}vOw, Formula II: Ba(ZrxMgyTaz)vOwor Formula III: Ba{(SnuZr1-u)x(ZntMg1-t)yNbz}vOw. The translucent ceramic has a refractive index of 1.9 or more and is paraelectric.
