A porous sintered body with an electrically conductive coating is provided. The sintered body has an open porosity in a range from 10 to 90%. The electrically conductive coating is bonded to the surface of the pores and is part of a heating device in a vaporizer. The electrically conductive coating lines the pores located in the interior of the sintered body so that when the sintered body is electrically connected and a current is applied, the current flows at least partially through the interior of the sintered body so that the interior of the sintered body is heated. A method for producing a porous sintered body with an electrically conductive coating is also provided.

Sintered body with electrically conductive coating

The glass composite has a linear thermal expansion coefficient &#x3b1;of 1.8&#xd7;10Kto 2.4&#xd7;10K, a glass transformation temperature Tg of less than 650&#xb0; C., and a composition, in weight percent based on oxide content, of: 5-9, BO; 1-3, NaO; 15-22, AlO; 61-68, SiO; 0.2-0.5, KO; and 5.5-8.5, MgO. It can be made by sintering a mixture of 40 to 60 wt. % of a borosilicate glass powder and 60 to 40 wt. % of a cordierite powder. The powder mixture can be used to make a glass solder for joining parts, to make a sintered body with thermal shock resistance, or for glazing or soldering PZT ceramics.
