【摘要】通过挤压法制备ZrO₂陶瓷纤维；采用参量变换法研究了PVA和甘油含量分别对纤维密度和收缩率的影响；并且对ZrO₂纤维的前躯体进行热重（TG）和差热（DTA）分析,对ZrO₂纤维进行扫描电镜（SEM）分析。且在实验中用溶胶取代粘结剂制备纤维,提高了纤维密度。更多还原

【Abstract】 In this paper zirconia ceramic fibers are prepared via extrusion.The influence on fibers density and shrinkage by PVA and glycerin content is studied via parameter-transformation procession.Furthermore,the precursor of zirconia fibers are analysed by TG and DTA,and scanning electron microscopy is performed,too.In the experiment binder is substituted by sol,which improves density of fibers.更多还原
