Barium chlorate hazardous waste. The Environmental Protection Agency (EPA) lists barium chlorate as hazardous. Barium chlorate Barium chlorate, Ba(ClO), is a white crystalline solid, the barium salt of chloric acid. It is an irritant and toxic, as are all soluble barium compounds. It is sometimes used in pyrotechnics to produce a green color. It also finds use in the production of chloric acid. Barium chlorate can be produced through a double replacement reaction between solutions of barium chloride and sodium chlorate: On concentrating and chilling the resulting mixture, barium chlorate precipitates. This is perhaps the most common preparation, exploiting the lower solubility
Barium borate 27% zinc oxide, and grade III is compounded with 18% of zinc oxide and 29% calcium sulfate. Barium borate shows synergistic performance with zinc borate. Barium borate is used as a flux in some barium titanate and lead zirconate EIA Class 2 dielectric ceramic formulations for ceramic capacitors, in amount of about 2%. The barium-boron ratio is critical for flux performance; BaBO content adversely affects the performance of the flux. Barium borate-fly ash glass can be used as radiation shielding. Such glasses are superior in performance to concrete and to other barium borate glasses. Barium borate Barium borate is an
