Barium Selenite

Barium selenite is a chemical compound with the formula BaSeO3. It is a white crystalline powder that is insoluble in water. Barium selenite is primarily used as a precursor for the preparation of other selenium compounds and in the production of glass.

Barium selenite has a tetragonal crystal structure and can exist in two forms: alpha and beta. The alpha form is stable at temperatures below 643 degrees Celsius, while the beta form is stable at higher temperatures.

Barium selenite is toxic and can cause severe irritation to the eyes, skin, and respiratory system. It should be handled with care and under appropriate safety precautions.

In terms of its chemical properties, barium selenite is a strong oxidizing agent and can react violently with reducing agents. It is also soluble in acids, forming toxic hydrogen selenide gas upon reaction with hydrochloric acid.

Overall, while barium selenite has important industrial applications, it should be handled with caution due to its toxicity and reactivity.
