[求助] ZnO压敏陶瓷XRD图分析

ZnO-Bi2O3系或者ZnO-Pr6O11系压敏陶瓷都掺杂有Co，Cr；但XRD图里为什么没有Co，Cr峰？是不是因为它们的峰值很小导致没有显示出来？还是？？？

感谢回答，谢谢！！！

请问这种打磨抛光腐蚀的技术有没有书籍或者review的专门介绍？求请赐教。...

其中写道：For microstructural observations, the sintered specimens
were cut diametrically using low speed diamond
saw. The cut pellets were mounted using conductive
resin, ground with 600–1000 grit SiC paper, and
finally polished to a 1-Am surface finish using diamond
paste. The surfaces were etched with 2% nital (2
vol.% nitric acid with alcohol) for about 2 min. Grain
sizes were measured directly from the micrographs of
the etched samples

其中写道：One side of samples was lapped and ground with SiC paper
and polished with 0.3m Al2O3 powder to a mirror-like surface.
The polished samples were chemically etched at 1HClO4:1000H2O
for 40 s. The surface microstructure was examined by a scanning
electron microscope (SEM, Hitachi S2400, Japan).
