Barium ferrite these species include BaFeO, BaFeO, and BaFeO. A one-step hydrothermal process can be used to form crystals of barium ferrite, by mixing barium chloride, ferrous chloride, potassium nitrate, and sodium hydroxide with a hydroxide to chloride concentration ratio of 2:1. Nanoparticles are prepared from ferric nitrate, barium chloride, sodium citrate, and sodium hydroxide. The typical preparation, however, is by calcining barium carbonate with iron(III) oxide: Barium ferrite has been considered for long term data storage. The material has proven to be resistant to a number of different environmental stresses, including humidity and corrosion. Because ferrites are already oxidized it can
Sterling v. Velsicol Chemical Corp. Sterling v. Velsicol Chemical Corp. Sterling v. Velsicol Chemical Corp., 855 F.2d 1188 (6th Cir. 1988), was an environmental lawsuit filed by citizens of Hardeman County, Tennessee, led by Steven Sterling, who sued Velsicol Chemical Corporation for contaminating their water supply through improper disposal of toxic chemicals. In August 1964, Velsicol Chemical Corporation acquired of rural land in Hardeman County, Tennessee. Velsicol used the site as a landfill for by-products from the production of chlorinated hydrocarbon insecticides at its Memphis, Tennessee, chemical manufacturing facility. Before Velsicol purchased the landfill site and commenced depositing chemicals into the ground, it neither conducted
