Title:
TRANSLUCENT ALUMINA SINTERED COMPACT HAVING SURFACE REINFORCING LAYER AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2014015362
Kind Code:
A
Abstract:

To provide a translucent alumina sintered compact which is improved in mechanical strength without impairing translucency thereof.

A ceramic powder layer is formed on a surface of a translucent alumina sintered compact by applying a slurry to the surface of the translucent alumina sintered compact or impregnating the translucent alumina sintered compact with the slurry. Thereafter, the translucent alumina sintered compact is sintered, and further the obtained sintered compact is pressure-sintered by hot isostatic pressing or the like, thereby obtaining a translucent alumina sintered compact having a ceramic layer with a thickness of 1-10 μm formed thereon.
