The invention discloses coatings for preparing barrier layers, preparation methods of the barrier layers and the barrier layers. The coatings for preparing the barrier layers comprise nitrate, a combustion improver and an aqueous solution, the nitrate comprises gadolinium nitrate and cerous nitrate, and the molar ratio of the gadolinium nitrate to the cerous nitrate is 1:9; and the molar weight of the combustion improver is 1.5-2 times that of metal ions. The preparation method of any one of the barrier layers comprises the following steps: coating any one of the coatings on an electrolyte sheet for presintering, decomposing nitrate to obtain GDC powder, and obtaining a barrier layer preform; coating the barrier layer preform with a sintering aid; and sintering the barrier layer preform to obtain the barrier layer. The invention also discloses the barrier layers, and the barrier layers are prepared by any one of the preparation methods of the barrier layer. 本发明公开了一种用于制备阻隔层的涂料、阻隔层的制备方法及阻隔层。一种用于制备阻隔层的涂料包括硝酸盐、助燃
