Used in the laboratory for the titration of weak acids, especially organic acids, due to its strong basicity and clear endpoint detection. Commonly employed in the synthesis of barium-containing compounds and in the production of lubricating oils by neutralizing acidic components. Also utilized in the sugar industry for the refining of beet sugar, where it helps in the precipitation of impurities. In addition, it serves in the manufacture of certain types of glass and ceramics, contributing to improved thermal and electrical properties. Its ability to absorb carbon dioxide from air makes it useful in gas purification processes.
