  • Publication number: 20200323040
    Abstract: An electrical resistor includes borosilicate particles, Si-containing particles, and pore parts. The pore parts are constituted by gaps between the borosilicate particles and the Si-containing particles and surround the borosilicate particles and the Si-containing particles. A honeycomb structure includes the electrical resistor. An electric heating catalytic device has the honeycomb structure.

  • Publication number: 20200222891
    Abstract: An electrically heated catalyst includes a honeycomb substrate, an electrode, and a joining section. The honeycomb substrate and the joining section include matrices and conductive fillers. The matrices contain borosilicate including at least one of an alkali metal and an alkaline earth metal. The joining section preferably has a softening point lower than that of the honeycomb substrate.
