Information
What is Barium Nitrate?
Barium nitrate is a nitrate salt of the alkaline earth metal barium. It has the formula Ba(NO3)2 and belongs to the group of nitrates.
Barium nitrate occurs as a colorless crystalline solid. It is harmful to health and a substance that is slightly hazardous to water. In a flame it produces the green flame color typical of barium and can be used as an oxidizing agent.
Barium nitrate decomposes at temperatures above 550 °C to form barium oxide, nitrogen, oxygen and nitric oxide. Due to the released oxygen and especially the released nitric oxide, barium nitrate is a good oxidizing agent.
Anhydrous barium nitrate crystallizes in the cubic crystal system in the space group Pa3 (space group No. 205) with the lattice parameter a = 811.84 pm. There are four formula units in the unit cell. The crystals are isotypical for strontium nitrate.
It is used in fluorescent screens for television receivers.
