采用“毛坯浆料法”在ＺｒＯ＿２（９％摩不含量ＭｇＯ）管状固体电解质基体表面制备了厚度为１～４μｍ的ＺｒＯ＿２（１０％摩尔含量Ｙ＿２Ｏ＿３）固体电解质涂层，并分别对此在本实验室和美国ＬｅｅｄｓａｎｄＮｏｒｔｈｒｕｐ公司进行了钢液低氧含量的测试。结果表明：涂层没有破坏基体的抗热震性；氧浓差电池电动势的重现性偏差山原来的±７ｍＶ变化到±２ｍＶ；电动势的绝对值提高１０ｍＶ左右；而比日本Ｔｏｒａｙ公司的同类产品提高３５ｍＶ，这说明ＺｒＯ＿２（１０％Ｙ＿２Ｏ＿３）涂层大大降低了基体电解质的表观电子电导。
The ZrO 2 (10% molar content Y_2O_3) solid electrolyte coating with the thickness of 1 ~ 4μm was prepared on the surface of ZrO_2 (9% MgO-free MgO) tubular solid electrolyte by the “blank slurry method” Room and the United States Leeds and Northrup company conducted a test of low oxygen content of liquid steel. The results show that the coating does not destroy the thermal shock resistance of the substrate. The reproducibility of the electromotive force of the oxygen concentration cell varies from ± 7mV to ± 2mV, and the absolute value of the electromotive force increases by about 10mV. Increased 35mV, indicating that the ZrO_2 (10% Y_2O_3) coating greatly reduces the apparent electron conductance of the matrix electrolyte.
