摘要
Successful deposition of ultra-thin ceramic membranes by the sol-gel process could lead to greatly improved electrolyte devices. The parameters of the sol-gel technique which affect film cracking and continuity have been investigated, and the effect of substrate conditions and substrate porosity have been determined. Crack-free yttria-stabilized zirconia films having thickness of approximately 0.2 to 0.5-mu-m have been deposited on continuous quartz substrates. Preliminary results have also indicated that continuous sub-micron electrolyte films can be deposited on porous substrates.
