摘 要: 采用前驅體浸漬轉化法制備氧化鋯纖維布制品，利用X射線衍射和掃描電鏡研究制備過程熱處理制度對樣品組織結構的影響。結果表明：氧化鋯纖維布制品具有與前驅體纖維布相同的物理形貌，其單根纖維光滑飽滿，直徑約為5~8 μm；組成纖維布的主晶相為t-ZrO2，平均晶粒粒徑約為15~30 nm；降低燒結溫度、加快升溫和冷卻速率，均有利于細化晶粒，減少次物相m-ZrO2和c-ZrO2的產生，但在一定程度上降低制品的致密度。

Abstract:Zirconia cloth was prepared by precursor process that oxidizes hydrated cellulose textiles impregnated with zirconium salts. The effect of heat treatment on the phase and microstructure of the cloth was studied by XRD and SEM. The results show that zirconia cloth has the same morphology with the precursor. Any individual fiber in the cloth has smooth surfaces and full core with the diameter of about 5−8 μm. The cloth is mainly consisted of tetragonal ZrO2 with average grain size of about 15−30 nm. With the decrease of sintering temperature and increase of heat rate and cooling rate, the grain size is fined, the amount of impurity phase m-ZrO2 and c-ZrO2 decreases, while the density is loosed.
