Fig.2 shows the X-ray diffraction patterns of the six samples.To confirm the LDH-NO3-CO3 whiskers,we compare these patterns with the quasi-diffraction patterns of LDH-NO3-CO3 whiskers(14-JCPDS 0191).Patterns of the six samples are identical in relative signal strength and standard diffraction profile.Next,we calculate the half peak width for(003):Sample 1 at0.82?,Sample 2 at 0.78?,Sample 3 at 0.55?,Sample 4at 0.38?,Sample 5 at 0.49?,and Sample 6 at 0.51?.The sharpest diffraction peak of Sample 4 for the(003),(006) ,and(009)planes proves that it possesses the best crystallinity.The crystallinities of Samples 1,2,3,5,and 6 are relatively poor.The order of crystallinity of the 6 samples ranks as follows:Sample 4>Sample 5>Sample 6>Sample 3>Sample 2>Sample 1.Table 1lists the maximum diffraction intensity and the corresponding d values of the 6 samples for the(003),(006) ,and(009)crystal planes.From Table 1,the d003value of Sample 4 is twice its d006 value and thrice its d009 value.These findings show that Sample 4 has a very neat board,whereas the multiple relationships for the other five samples were relatively poor.Thus,we could determine the minimum half peak width of Sample 4 based on the diffraction intensity.The crystallinity of Sample 4 is the highest and that of Sample 1 is the lowest.In addition,from the diffraction curve,besides Sample 4,all the other samples have a hybrid peak,which indicates they contain impurities.
