  • Patent number: 10440990
    Abstract: A composite heat source for use in a smoking article is provided, including a non-combustible porous ceramic matrix; and a particulate combustible fuel embedded within the non-combustible porous ceramic matrix. The non-combustible porous ceramic matrix is formed from one or more particulate materials having a median D50 particle size at least five times less than the median D50 particle size of the particulate combustible fuel. Preferably, the non-combustible porous ceramic matrix includes one or more transition metal oxides.
    Type: Grant
    Filed: July 27, 2017
    Date of Patent: October 15, 2019
    Assignee: Philip Morris Products S.A.
    Inventors: Friedrich Raether, Holger Friedrich, Jens Baber

  • Patent number: 7399718
    Abstract: The invention relates to a multilayer material comprising (a) a first layer that consists of plaster or that substantially consists of plaster, and (b) at least one second layer, comprising a sandwich textile fiber material. The fibers of said material are interlinked in a mechanically stable manner, are incombustible and weather-proof and the interspaces are filled with a finely porous material. The second layer has a diffusion-equivalent air layer thickness of not more than 2.0 m and is water-impermeable at a water pressure of at least 100 mm water column. The inventive material can be used outdoors due to its properties. The invention further relates to methods for producing such a material.
