摘要： A solid electrolyte is composed primarily of a component expressed by a composition formula of Lia+dMbXcAeOf by using values a to f that are greater than 0, where M is an element serving as a trivalent cation, X is a halogen element, and A is a sulfur element or a phosphorus element, wherein 0.8c≤(a+3b)≤1.2c and 1.6f≤(d+n×e)≤2.4f are satisfied, where when A is a sulfur element, n is 4 or 6, and when A is a phosphorus element, n is 5.

摘要： The composite sintered body includes AlN and MgAl2O4. The open porosity of the composite sintered body is lower than 0.1%. The relative density of the composite sintered body is not lower than 99.5%. The total percentage of the AlN and the MgAl2O4 contained in the composite sintered body is not lower than 95 weight percentage and not higher than 100 weight percentage. The percentage of the MgAl2O4 contained in the composite sintered body is not lower than 15 weight percentage and not higher than 70 weight percentage. It is thereby possible to provide a high-density composite sintered body having high plasma corrosion resistance, high volume resistivity, and high thermal conductivity.
