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

gollark: They mostly just list various kinds of media, have search, and let you share files between apps.
gollark: They have files *internally*, obviously, but you can't do much with them.
gollark: Except phones and such basically do not files.
