Some of these applications are as under:
(i) to detect and photograph defects within a body i.e. in its internal structure such as metals, machine parts intended for withstanding high pressures, cracks in wood, porcelain and other insulators, defects in diamonds and other precious stones, in moulds, forgings and castings etc.
(ii) to analyses the structure of alloys and other rcomposite bodies by determining the crystal form in an ingot with the help of diffraction of X-rays. In this way, alloys like cobalt-nickel,steel, bronze, dur-aluminium, artificial pearls and old paintings have been analysed.
(iii) to study the structure of rubber, cellulose and plastics. The diffraction of X-rays by these substances leads to valuable information about their molecular grouping.
