  • Patent number: 9673381
    Abstract: The invention provides a lead titanate coating and a preparing method thereof. According to the method, mixed powder is sprayed on the surface of a matrix, and through polarization, the lead titanate coating is acquired. The mixed powder comprises PbTiO3 powder, PbO powder and Al powder. Lead titanate (PbTiO3) is a kind of ferroelectric material, and can be used for preparing a piezoelectric sensor. Besides, the PbO powder and the Al powder are added, so that the piezoelectric property of the lead titanate coating can be improved. Since the lead titanate coating prepared by the present invention can be combined with the matrix closely and the intensity of piezoelectric signal is high, it can be widely applied to mechanical parts, such as a piston ring, a cylinder, a gear, and the like, to dynamically monitor the service situations of the parts better.

  • Patent number: 9312070
    Abstract: A multilayer ceramic capacitor has multiple laminated dielectric ceramic layers made of a dielectric ceramic, internal electrodes formed between the dielectric ceramic layers, and external electrodes electrically connected to the internal electrodes, wherein generation of cracks in the dielectric layer due to expansion of the internal electrode is suppressed by causing ceramic grains having a crystal axis ratio c/a higher than that of the ceramic grains constituting the dielectric layer to be present in non-contiguous parts of the internal electrodes between the dielectric ceramic layers, and by harnessing the stress-mitigating effect of domain switching involving these ceramic grains.
