Abstract:
1. A method of producing a translucent ceramic having a refractive index of equal to or more than 1.9 and being paraelectric and comprising a polycrystalline oxide perovskite crystal phase, the method comprising the steps of: molding a ceramic material powder and a binder into a predetermined shape to thereby yield a translucent ceramic green compact comprising a perovskite crystal phase represented by the formula ABO bringing the ceramic green compact into contact with a ceramic powder having substantially the same composition with the ceramic material powder, and firing the ceramic green compact in contact with the ceramic powder to thereby yield said translucent ceramic, wherein the perovskite crystal phase is a member of the group consisting of
