PROBLEM TO BE SOLVED: To provide a method by which the lattice constant of a single crystal can be measured accurately and quickly. SOLUTION: In a method for measuring lattice constant of single crystal, the lattice constant of a single crystal is measured by using a bond method in such a way that the range of angle to be measured is decided from the measured result of the peak profile of diffracted X rays to a specific lattice plane when the peak profile is measured at and after the second time in the case the peak profile is measured a plurality of times for accurately finding the lattice constant of the single crystal by X-ray diffraction. |
