웹Barium carbonate is a chemical compound of barium.It is used in rat poison, bricks, ceramic glazes and cement. Barium is a metallic alkaline earth metal with the symbol Ba, and atomic number 56. It never occurs in nature in its pure form due to its reactivity with air, but combines with other chemicals such as sulfur or carbon and oxygen to form barium compounds that … 웹2024년 5월 29일 · Because pure barium reacts immediately with oxygen and water vapor to produce barium oxide when exposed to air, barium does not naturally occur in an uncombined state. Barium compounds are found primarily in two mineral ores— barite , which contains the sulfate compound, and witherite , which contains barium carbonate.
