Properties
Caesium tungstate forms colorless crystals, which are strongly hygroscopic. The phase transition occurs at 536 ℃, a transition from orthorhombic to hexagonal crystals.
Preparation
Caesium tungstate is obtained by the reaction between caesium chloride (CsCl) and silver tungstate (Ag2WO4).
Hazards
Caesium tungstate has acute toxicity and it may cause irritation. It may cause inflammation upon contact with skin and eyes.
