  • METHOD FOR REMOVING BORON FROM BORON-CONTAINING WASTE WATER
    Publication number: 20160340216
    Abstract: A method for removing boron from boron-containing waste water includes performing oxidation/coagulation treatment on the boron-containing waste water in the presence of an oxidant (such as hydrogen peroxide) and a coagulant (such as barium hydroxide) to greatly reduce the boron content of the boron-containing waste water and then removing residual boron therefrom by an ion-exchange resin or reverse osmosis, such that the waste water thus treated meets effluent standards.

  • SBTN ferroelectric thin film and method for producing same
    Patent number: 6503374
    Abstract: A novel SBTN (SraBibTacNbdOx) thin film which exhibits satisfactory ferroelectric properties is disclosed, wherein a lies between 0.5 and 1, b lies between 2 and 2.7, c lies between 1 and 1.4, d lies between 0.6 and 1.1, and x lies between 8 and 10. The composition of Sr0.8Bi2.5Ta1.2Nb0.9Ox wherein x lies between 9 and 10 is preferred. The Sr0.8Bi2.5Ta1.2Nb0.9Ox thin film is formed by two-target off-axis RF magnetron sputtering at a temperature down to about 600° C. One target is formed of Sr0.8Bi2.2Ta1.2Nb0.8O9, and the other target is formed of Bi2O3.
