Introduction
Terbium sulfate is a white crystalline powder. When it is hot to 360 ℃, it loses crystal water and becomes anhydrous salt. It can be dissolved in water and can be used for the preparation of lead-free piezoelectric ceramics.
Solubility in water (g/100ml)
Dissolved grams per 100 ml of water:
3.56g/20℃
Production method
dissolve high purity Tb2O in dilute hydrochloric acid, add dilute sulfuric acid slightly more than the reaction measure to the solution, and then add a large amount of 95% ethanol to the solution to precipitate the crystal of terbium sulfate, filter out the precipitate and wash with 95% ethanol until there is no chloride ion and free acid, and cool and dry in the air.
