Barium green color. Barium sulfate is used as an insoluble additive to oil well drilling fluid, as well as in a purer form, as X-ray radiocontrast agents for imaging the human gastrointestinal tract. The soluble barium ion and soluble compounds are poisonous, and have been used as rodenticides. Barium is a soft, silvery-white metal, with a slight golden shade when ultrapure. 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
Lithium chlorate density flow batteries. Lithium chlorate has a very low melting point for an inorganic ionic salt. Lithium chlorate Lithium chlorate is the inorganic chemical compound with the formula LiClO. Like all chlorates, it is an oxidizer and may become unstable and possibly explosive if mixed with organic materials, reactive metal powders, or sulfur. It can be manufactured by the reaction of hot, concentrated lithium hydroxide with chlorine: 3 Cl + 6 LiOH → 5 LiCl + LiClO + 3 HO Lithium chlorate has a very high solubility in water. It is also a 6-electron oxidant. Its electrochemical reduction is facilitated
