Abstract: Provided are a ceria-based composition including ceria or metal-doped ceria, lithium salt, and optionally, bismuth oxide, ceria-based composite electrolyte powder, and a sintering method and sintered body using the same. Particularly, the lithium salt is present in an amount more than 0 wt % and equal to or less than 5 wt %, and bismuth oxide is present in an amount more than 0 wt % and equal to or less than 10 wt %. It is possible to reduce sintering temperature by adding a low-melting point and/or volatile compound to a ceria-based material. In this manner, it is possible to ensure a high composite sintering density, for example, of 95% or more even at a temperature, for example, of 1000° C. or lower, which is significantly lower than the conventional sintering temperature of 1500° C. in the case of a ceria-based material alone.

Abstract translation: 提供了包括二氧化铈或金属掺杂的二氧化铈，锂盐和任选的氧化铋，二氧化铈类复合电解质粉末和使用其的烧结方法和烧结体的二氧化铈基组合物。 特别地，锂盐的存在量大于0重量％且等于或小于5重量％，并且氧化铋以大于0重量％且等于或小于10重量％的量存在。 可以通过向二氧化铈基材料中添加低熔点和/或挥发性化合物来降低烧结温度。 以这种方式，即使在例如1000℃以下的温度下也可以确保高的复合烧结密度，例如为95％以上，这明显低于常规烧结温度为1500 在仅有二氧化铈基材料的情况下。

Abstract: The present invention relates to a hydrogen production reactor comprising a high-efficiency composite having a high thermal conductivity and an antioxidant property. Specifically, the hydrogen production reactor comprises: a first region in which a combustion reaction of fuel occurs; a second region in which a hydrogen extraction reaction occurs; a metal substrate that partitions the first region and the second region; and a coating layer that comprises boron nitride (BN) and is formed on at least one surface of the metal substrate, wherein heat generated in the first region is transferred to the second region through the metal substrate.
