Abstract

The investigation of the effect of initial salt counter-ion on the result of hydrothermal
processing of yttrium salts is presented. Powder X-ray diffraction analysis and scanning
electron microscopy have been used to characterize the properties of the products. It has
been established that 3–6 μm crystals of Y₂(OH)_5.14(NO₃)_0.86·H₂O structure are formed from yttrium nitrate and 200–500 nm crystals of Y₂(OH)4_.86Cl_1.14·1.07H₂O structure are formed from yttrium chloride.
