Ceramic sintered body.

摘要

A ceramic sintered body comprises a first material comprising at least one of precursor and metastable material of the final sintered body and a second material derived from the first material and serving as additive to be added to the first material by 0.1% to 100% on particle number basis. The ceramic sintered body is sintered in a process which comprises the steps of providing a first material which comprises at least one of precursor and metastable material of the final sintered body, adding a second material and sintering mixture of the first and second materials.
