  1. The parameters of impregnation are as follows : ph is about 3, the range of temperature is from 20 to 45, and the time is about 2 to 6 hours. after the necessary treatments, zirconia cloths had the optimal strength when the diameters of zirconia fibers were controlled in 4um to 7um, and the sizes of zirconia grains were in 50nm to 100nm. the affec - ting factors were discussed and the liner regression analysis of the cloths was made, from w hich they show that the diameters and grain sizes have the significant influences on zirconia cloths. the obtained zirconia cloths have been accepted for use in nickel - hydrogen batteries by practical use

    研究結果表明：粘膠類纖維布最適合制備氧化鋯纖維布的前軀體；鋯液濃度以飽和溶液為宜；浸漬工藝參數為ph值3左右，溫度20 45 ，時間2 6小時；多餘鋯鹽的去除、浸鋯液后纖維布的整平處理及平燒施應力燒成有利於氧化鋯纖維布的柔軟及平整; 200 600燒成溫度段應緩慢燒成，控制氧化鋯纖維直徑在4 7 m ，氧化鋯晶粒尺寸50 100nm時氧化鋯纖維布的強度最好。
