Ti$_{2}$O$_{2}$(C$_{2}$O$_{4}$)(OH)$_{2}$ . H$_{2}$O의 제조 및 특성평가

Preparation and characterization of Ti$_{2}$O$_{2}$(C$_{2}$O$_{4}$)(OH)$_{2}$ . H$_{2}$O

During studies of the ripening reaction of titanium oxalate, a new crystalline phase has been found. The crystal system was determined to be orthormbic with space group $C222_1$. The unit cell parameters were refined to a=10.503(2)$\AA$ b=15.509(3)$\AA$ c=9.7000(1)$\AA$. The chemical formula of the crystal is Ti$_{2}$O$_{2}$(C$_{2}$O$_{4}$)(OH)$_{2}$. H$_{2}$O. When heated to temperatures between 31$0^{\circ}C$ and 38$0^{\circ}C$, the material became amorphous. Heated above 41$0^{\circ}C$ converted it into anatase-type titanium dioxide.
