Barium

Barium (Ba) is a soft, silvery alkaline earth metal with high chemical reactivity, especially with air and water. It does not occur naturally as a free element due to its reactivity, instead being found in minerals such as barite (BaSO₄) and witherite (BaCO₃). Barium has a melting point of 727 °C and is known for its high density and ability to absorb X-rays. Due to its unique properties, it plays a critical role in scientific and industrial applications that range from vacuum tube technology to radiological imaging.

Goodfellow offers pure barium (Ba) products designed for use in both industrial processes and scientific research. One of its most prominent uses is in the production of barium sulfate (BaSO₄), which serves as a contrast agent in medical imaging techniques such as X-rays and CT scans. This compound’s radiopacity makes it ideal for enhancing image clarity during diagnostic procedures. In the oil and gas industry, barium compounds are used as weighting agents in drilling fluids to stabilize wellbores during extraction processes. Additionally, barium finds applications in electronics manufacturing, particularly in vacuum tubes and cathode ray tubes (CRTs), where it acts as a getter material to remove residual gases. Advanced technologies benefiting from barium include energy storage systems like batteries and supercapacitors, where it contributes to improved performance and efficiency. Goodfellow’s barium products enable researchers to explore new frontiers in materials science while supporting critical industrial applications that rely on its unique properties.
