Hydrogen permeance of Ce0.8Y0.2O1.9/SiC membrane.

SiC is a promising material for various inorganic membranes because there are properties such as high thermal conductivity, thermal shock resistance and high mechanical strength. Due to these advantages, SiC is also suitable for gas and liquid separation filter material. The SiC used as a support membrane and then added Ce0.8Y0.2O1.9 composite powder to effect catalyst and improve porous. The Ce0.8Y0.2O1.9 composite powder was synthesized with yttrium (III) nitrate hexahydrate and cerium(III) nitrate hexahydrate by sol-gel method. The Ce0.8Y0.2O1.9/SiC membrane was prepared from the purified SiC ceramic and the synthesized Ce0.8Y0.2O1.9 composite powder with aid of hydridopolycarbosilane (HPCS) as a binder, followed by heat-treatments. This membrane was characterized by XRD, FE-SEM, EDXS and BET surface analysis. Thermal diffusivity and hydrogen permeance for this membrane will be discussed.
