On Hydrated Strontium Hafnate

For the first time, strontium hafnate of the composition SrHfO3 · 2H2O was isolated from hafnium-containing alkali solutions. This compound was the only solid product of the reaction in the range of the strontium-to-hafnium molar feed ratios studied from 0.52:1 to 1.74:1 under various synthesis conditions (T = 40-145°C, 50.0-67.0 wt % NaOH). The compound crystallizes in the cubic system with a varied within 4.072-4.144 Å. Water enters the compound as molecules or hydroxide groups and insignificantly influences its structure. Dehydration decreases a.
