Boron sulfide is yellow to white crystal or amorphous powder. The other name is boron trisulfide or boron(III) sulfide. It turns paste after heating. B2S3 resolve in moist air. It faintly dissolve in phosphorus trichloride and sulfur dichloride. It tend to hydrolyze and form boric acid and hydrogen sulfide. B2S3 resolve in alcohol too. Iron boride is the raw material.
