Provided is a solid electrolyte which is identified as 3LiOH·LiSOby diffractometry. The solid electrolyte further contains boron.

Solid electrolyte and method for producing solid electrolyte

A lithium ion conductive material has a composition formula of Li(OH)FClBr, where 1.8&#x2264;a&#x2264;2.3, b=a &#x2212;c&#x2212;1, 0&#x3c;c&#x2264;0.30, 0&#x3c;d&#x3c;1, and includes an antiperovskite-type crystal phase. The lithium ion conductive material is manufactured, for example, by heating LiOH, LiF, LiCl, and LiBr at a temperature not lower than 250&#xb0; C. and not higher than 600&#xb0; C. for 0.1 hours or more while stirring them at a molar ratio of 1:X:Y:Z (where 0.03&#x2264;X&#x2264;0.3, 0.2&#x2264;Y&#x3c;1.1, 0&#x3c;Z&#x3c;1) under an Ar gas atmosphere.

The composite sintered body includes AlN and MgAlO. 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 MgAlOcontained in the composite sintered body is not lower than 95 weight percentage and not higher than 100 weight percentage. The percentage of the MgAlOcontained 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.
