An X-ray Diffraction Studies of Thorium Silicate

Thorium silicate has been prepared during the course of hydrolysis of thorium salt solution at 180° C in sealed pyrex glass tubes. An attempt has been made to study the crystal structure of this substance. The system belongs to tetragonal system with space group: D194h—I4/amd. The values of ao and co are 7.00 and 6.32 in angstrom respectively. A detailed theoretical calculation of the intensity has been done and the positions of the atoms have been assigned.
