  • Patent number: 8079256
    Abstract: In a gas sensor with at least two electrodes and with a sensor body which is connected thereto and is composed of a gas-sensitive material, in addition to pores which may already be present, second cavities are provided in the sensor body. The second cavities may be suitable on account of their size to facilitate and accelerate the distribution of gas molecules in the sensor body and to thus improve the time response of the gas sensor.
    Type: Grant
    Filed: February 22, 2006
    Date of Patent: December 20, 2011
    Assignee: Testo AG

  • Patent number: 5958815
    Abstract: A method of making porous ceramics of lead titanate (PT) or lead zirconate PZT) of a Pb(Zr.sub.x Ti.sub.1-x) O.sub.3 compound from a gel made by mixing at least 2.5 equivalents of water based on the compound with a solution prepared from a polar solvent having complexing and chelating properties, one or more Pb(II) and PB(IV) carboxylates and at least one compound including titanium and zirconium of the general formula M(OR).sub.4 where M is titanium or zirconium and R is similar or different groups representing at least one of a straight chain, cross-linked and cyclic alkyl and alkenyl group with 1 to 10 carbon atoms, aging the resulting gel beyond its gel point, replacing the solvent in the pores of the gel by a chelating solvent, drying the resulting gel under supercritical conditions and tempering the resulting aerogel.
