Abstract

Sinterability and microstructure of fluorite-type fluoride solid solution (Sr_{1 - x}La_xF_{2 + x}) were studied for two ceramics: one by reaction hot-pressing of mixed fluoride powder and the other by hot-pressing of the solid solution powder synthesized hydrothermally. The latter ceramic was densified to 99% of relative density with pore-free and uniform grain size (40 μm) as the same of pure SrF₂. Fracture toughness, K_IC of this ceramics (Sr_{1 - x}La_xF_{2 + x}) ranged 0·2 to 0·7 MPam^{1 2}.
