| 内容： | Sintered alumina-based ceramic objects exhibiting high hardness and density combined with low porosity, and a process for making them are provided. The process includes mixing alumina with a grain growth-inhibiting material, and with a glue and pressing wax material, in a liquid medium in which the last two materials are soluble while the alumina is not, sequentially removing essentially all of the liquid medium in order to form a ready to press (RTP) free flowing powder, pressing the RTP powder to a "green body", de-waxing and sintering the green body. The so obtained sintered objects are suitable for ballistic protection, as well as for other uses. |
