Abstract: A sintered ceramic component can have a final composition including at least 50 wt. % MgO and at least one desired dopant, wherein each dopant of the at least one desired dopant has a desired dopant content of at least 0.1 wt. %. All impurities (not including the desired dopant(s)) are present at a combined impurity content of less than 0.7 wt. %. A remainder can include Al2O3. The selection of dopants can allow for better control over the visual appearance of the sintered ceramic component, reduces the presence of undesired impurities that may adversely affect another part of an apparatus, or both. The addition of the dopant(s) can help to improve the sintering characteristics and density as compared to a sintered ceramic component that includes the material with no dopant and a relatively low impurity content.

Abstract: Embodiments of the present disclosure relate to a hot press and methods of using the hot press. In an embodiment, the hot press can include a pressing element including a flared body. In another embodiment, the hot press can include a compression surface. The compression surface can include a first layer including a monocrystalline material and a second layer including a polycrystalline material, wherein the monocrystalline material and the polycrystalline material include a same primary compound. In a further embodiment, a sample including more than one layer of ceramic oxide material can be hot pressed without a die.
