Abstract:
K-value method of X-ray powder diffraction was used to quantify the α-Co with the hcp structure in cobalt. In this article,α-Al2O3 was chosen to be the reference material while the α-Co with high purity as the standard sample. The results showed that K-value was 4.58 which was used to quantify the α-Co in 3 cobalt samples. The relative standard deviation and the recovery rate of 3 cobalt samples evaluate the accuracy of the K-value method.
