Effect of hot-pressing temperature on the properties of aluminum-magnesium spinel optical ceramic

摘要

In this paper, we describe the results of research on the effect of the hot-pressing temperature on the spectral properties, density, and microhardness of aluminum-magnesium spinel ceramic. We fabricated experimental samples of a high-density ceramic (density exceeding 99 of the theoretical density) with high transparency over a broad spectral range by using a combination of cold pressing of nanopowders and subsequent hot pressing of the blanks.
