Bariumoxid ist ein farbloser Feststoff, der bei 1918 °C schmilzt. Mit Wasser reagiert es unter. Barium is a soft, silvery-white metal, with a slight golden shade when ultrapure.: 2 The silvery-white color of barium metal rapidly vanishes upon oxidation in air yielding a dark gray oxide layer. Barium has a medium specific weight and good electrical conductivity. Ultrapure barium is very difficult to prepare, and therefore many properties of barium have not been accurately measured yet Barium Oxide (BaO) is a white ionic crystal that has a non-flammable nature. It is a cubic structured compound that can be prepared by different methodologies, such as thermal decomposition of barium nitrate, and by heating barium carbonate with carbon black or tar. Application BaO can be used in a variety of applications such as
